Si5338-EVB

Si5330/34/35/38 E VALUATION B OARD U SER ’ S G UIDE

Description

The Si5338-EVB is used for evaluating the Si5330/34/

35/38 family of any-frequency, any-output clock generators and clock buffers.

EVB Features

 Fully powered from a single USB port.

 Onboard 25 MHz XTAL allows standalone asynchronous operation on the Si5334/35/38.

 GUI programmable V_DDsupply allows device to operate from 3.3, 2.5, or 1.8 V.

 GUI programmable V_DDO supplies allow each of the four outputs to have its own supply voltage

selectable from 3.3, 2.5, 1.8, or 1.5 V

 GUI-controlled voltage, current, and power measurements of V_DD and all four V_DDO supplies.

 Voltage supply jumpers allow easy access for use of external supplies or current measurements.

 Input signal jumpers allow external control of pin functions such as output enable, phase inc/dec, frequency inc/dec, and I2C_LSB.

1. Functional Block Diagram

A functional block diagram of the EVB is shown in Figure 1. The MCU performs the USB to I²C conversion, controls the voltage regulators, monitors the INTR pin, and controls the four status LEDS. It also provides control of the eight input pins when the INx_CTRL jumpers are populated. There are five programmable voltage regulators (VDD, VDDO0, VDDO1, VDDO2, VDDO3), which supply power to the Si533x device. VDD and VDDO jumpers allow the option of powering the device from external supplies, or as a convenient point for measuring current. I²C jumpers allow disconnection of the Si533x device from the I²C bus to allow external control from another I²C master.

For the Si5334, Si5335, and Si5338 devices, the EVB is shipped with an onboard 25 MHz XTAL to allow stand-alone asynchronous operation. For Si5335 emulation, synchronization to an external reference is done via IN1 and IN2. Removal of the XTAL and addition of two 0 ohm resistors is required. IN3, IN4, IN5, and IN6 are not available as external clock inputs for Si5335.

2. Quick Start

1. Install the ClockBuilder Pro software.

2. Connect a USB cable from the EVB to the PC where the software was installed.

3. Leave the jumpers as installed from the factory, and launch ClockBuilder Pro.

3. Jumpers

The Si5338-EVB is shipped with jumpers installed on the following positions:

VDD—Connects the Si533x VDD pin to the VDD programmable voltage regulator.

VDDO0—Connects the Si533x VDDO0 pin to the VDDO0 programmable voltage regulator.

SCL—Connects the Si533x SCL pin to the I²C bus from the MCU.

SDA—Connects the Si533x SDA pin to the I²C bus from the MCU.

The INx-CTRL jumpers are optional jumpers for enabling MCU control of the Si533x input pins. This feature may be available in future software releases.

4. Status LEDS

There are four status LEDs on the Si5338-EVB:

RDY (Green)—Indicates that the EVB is operating normally. This LED should always be on.

I²C (Green)—Indicates when there is active I²C communication between the MCU and the Si533x device or between the MCU and voltage regulators.

USB (Green)—Indicates when there is active communication between the PC and the MCU over the USB bus.

INTR (Red)—The MCU has detected that the interrupt pin of the Si533x device is enabled. The most probable cause for an interrupt is because the Si533x has lost its input signal or the PLL has lost lock. The

“Status” tab of the GUI will identify the event that caused the interrupt to occur.

5. Inputs

The Si5338-EVB has six SMA connectors (IN1-IN6) for receiving external signals. Two of the signals are differential, and two are single-ended.

5.1. Differential Inputs (IN1/IN2, IN5/IN6)

The differential inputs only need a differential voltage swing of 300 mV to operate, which makes them compatible with most differential signal types. See “AN408: Termination Options for Any-Frequency, Any-Output Clock Generators and Clock Buffers—Si5338, Si5334, Si5330”, or Si5335 data sheet if applicable, for details on interfacing with compatible signal types. It is also possible to lock the Si5334/35/38 to an external signal generator using one side of the differential input and grounding its complementary side. Take care not to exceed the max differential voltage of 1.2 V on these inputs. The board is shipped with a 25 MHz XTAL connected to IN1/IN2. The XTAL removal and resistor changes are required for Si5335 evaluation with an input clock since only IN1 and IN2 are available for input clocking with Si5335. Note that regardless of device, any external input to IN1 & IN2 must be limited to 1.2 V peak-to-peak (see Figure 2 for resistor locations). When evaluating the Si5330, the XTAL must be removed. The differential input on pins IN5/IN6 is ac-coupled with a 100 line termination (R39).

Figure 2. Optional Termination Resistors for Differential Inputs IN1/IN2

5.2. Single-Ended Inputs (IN3, IN4) [Not supported in Si5335]

These inputs are dc-coupled to the device. They are compatible with a signal swing as low as 100 mV and a maximum of 3.63 V. The signal should have a minimum amount of dc bias to ensure that it is never below ground level.

The EVB provides pads for optional input terminations. These may be necessary when interfacing to SSTL and HSTL signals.

Note: For details on populated vs. non-populated components, refer to "8. Bill of Materials" on page 9.

(5)

6. Outputs (CLKxA/CLKxB)

Each of the four differential output drivers is capacitively coupled to the SMA connectors; so, the output signal will have no dc bias. If a signal with dc bias is required, the ac coupling capacitors can be replaced with a 0 resistor.

The EVB provides pads for optional output terminations. These may be necessary when interfacing to SSTL and HSTL signals.

6.1. Evaluating LVPECL Output Clocks

The EVB by default is populated to allow evaluating of all output clock formats with the exception of LVPECL outputs. To evaluate LVPECL signals on the Si5338-EVB, a few components must be soldered down on the board.

Take CLK0 for example of. Note that CLK0 has R85, R121/R122, R1/R4, R2/R5, R3/R6, C4/C7, and C15/C17 attached to the nets of interest. The EVB comes with only R121/R122 and C15/C17 installed. This allows support of all output types except LVPECL.

Evaluating an ac-coupled LVPECL clock on CLK0 requires a bias resistor of 130 or 200 to ground on each of the output lines depending on driver VDDO. Refer to AN408, or Si5335 data sheet if applicable, for termination details.

Make the following changes depending on the CLK0 VDDO voltage:

For 3.3 V LVPECL (ac-coupled)

ꞏ Place 200 resistors in place of R1 and R4.

ꞏ Place 0 resistors in place of C4 and C7.

For 2.5 V LVPECL (ac-coupled)

ꞏ Place 130 resistors in place of R1 and R4.

ꞏ Place 0 resistors in place of C4 and C7.

The LVPECL output may also be dc-coupled to an LVPECL receiver. To dc-couple the CLK0 output, make the component changes below. Note that R2, R3, R5, and R6 depend on VDDO.

Place 0 resistors in place of C15 and C17.

Place 50 resistors in place of R1 and R4.

Place C4 and C7

Select R2 and R3 (and similarly R5 and R6) to give a termination voltage of VTT = VDDO – 2 V.

For LVPECL termination on CLK1, 2, and 3 follow the guidelines above and refer to the schematics in “7.

Si5338-EVB Schematics” as needed.

6.2. Evaluating SSTL/HSTL Output Clocks

To support SSTL/HSTL outputs, either single-ended or differential, replace the output dc blocking capacitors with a 0 resistor. For example, for CLK0 output, replace C15 with 0  resistor for single-ended, or replace both C15 &

C17 with 0 for differential output. Do the same for CLK1,2,3 as needed. Remember to properly terminate at the receiver input.

The Si5338-EVB can support on-board termination of SSTL/HSTL outputs, if on-board terminated, measurement of the clock output at the SMA connector would require a high impedance measurement device to prevent overloading of the output. If on-board output termination is desired, the following components must be installed (using CLK0 as an example.)

For 1.8 or 2.5 V V_DDO: R2 = 2 k, R3 = 2 k, R1 = 50 , C4 = 0.1 µF For 3.3 V V_DDO: R2 = 2.42 k, R3 = 2 k, R1 = 50 , C4 = 0.1 µF

Follow similar guidelines for CLK1,2,3 as required. Refer to AN408, or Si5335 data sheet if applicable, for more details on clock termination.
