SI5348-D-EVB

UG511: Si5348-D Evaluation Board User's Guide The Si5348-D-EVB is used for evaluating the Si5348 Network Synchronizer Clock for SyncE/1588 and Stratum 3/3E applications. The device revision is distinguished by a white 1 inch x 0.187 inch label with the text “SI5348-D-EB” in the lower left-hand corner of the board. (For ordering purposes only, the terms “EB” and “EVB” refer to the board and the kit respectively. In this document, the terms are synonymous in context.) The Si5348 contains three independent DSPLLs in a single IC with programmable jitter attenuation bandwidth on a per DSPLL basis. The Si5348-D-EVB supports three independent differential input clocks, two independent CMOS input clocks, and seven independent output clocks via onboard SMA connectors. The Si5348D-EVB can be controlled and configured via a USB connection to a host PC running Skyworks’ next generation ClockBuilder® Pro (CBPro) software tool. Test points are provided on-board for external monitoring of supply voltages.

External Reference Input (XA/XB) An external timing reference (48 MHz XTAL) is used in combination with the internal oscillator to produce an ultra-low jitter reference clock for the DSPLL and for providing a stable reference for the free-run and holdover modes. The Si5348-D-EVB can also accommodate an external reference clock instead of a crystal. To evaluate the device with an external REFCLK, C111 and C113 must be populated and XTAL Y1 removed (see figure below). The REFCLK can then be applied to SMA connectors J39 and J40. Figure 4.1.

Clock Input and Output Circuits 5.1 Clock Input Circuits (REF/REFB, IN0/IN0B-IN2/IN2B, IN3, IN4) The Si5348-D-EVB has eight SMA connectors (REF/REFB, IN0/IN0B–IN2/IN2B) for receiving external differential clock signals. The REF/REFB differential input clock is intended to support a TCXO or OCXO, such as the included SiOCXO1-EB, which determines the Si5348’s wander performance. (Please note that this input clock is different from the optional reference clock that may be applied at XA/XB.) All differential input clocks are terminated as shown in the figure below. The only exception is that the terminating 49.9 Ω resistor for REF is not installed. This is R84 corresponding to IN0's R76 in the figure below. The reason for this exception is that single-ended TCXOs and OCXOs typically cannot drive a 50 Ω load. Note that input clocks are ac-coupled and 50 Ω terminated. This represents four differential input clock pairs. Single-ended clocks can be used by appropriately driving one side of the differential pair with a single-ended clock. For details on how to configure inputs as single-ended, please refer to the Si5348 data sheet. Figure 5.1. Differential Input Clock Termination Circuit In addition, the Si5348-D-EVB supports two SMA connectors (IN3, IN4) for receiving external single-ended LVCMOS clocks. Each of these clocks connects to its respective Si5348 pins via a single installed 0 Ω resistor. There are no other termination components on the EVB. 6 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 1.0 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • January 9, 2022 6 UG511: Si5348-D Evaluation Board User's Guide • Clock Input and Output Circuits 5.2 Clock Output Circuits (OUTx/OUTxB) Each of the 14 output drivers (seven differential pairs, OUT0/OUT0B—OUT6/OUT6B) is ac-coupled to its respective SMA connector. The output clock termination circuit is shown in the figure below. The output signal will have no dc bias. If dc coupling is required, the ac coupling capacitors can be replaced with a resistor of appropriate value. In particular, if differential pair OUT6/OUT6B is configured for 1 Hz output, then the AC coupling output capacitors, C166 and C168, each need to be replaced by a 0 Ω resistor. (These capacitors are the respective counterparts of the OUT0/OUT0B output capacitors, C25 and C27, in the figure below.) The Si5348-D-EVB provides pads for optional output termination resistors and/or low-frequency capacitors. Note that components with schematic “NI” designation are not normally populated on the Si5348-D-EVB and provide locations on the PCB for optional dc/ac terminations by the end user. Figure 5.2.

These jumpers, together with the components installed, configure the evaluation board to obtain all +5 V power solely through the main USB connector at J37. This setup is the default configuration and should normally be sufficient. The general guidelines for single USB power supply operation are listed below: • Use either a USB 3.0 or USB 2.0 port. These ports are specified to supply 900 mA and 500 mA respectively at +5 V. • If you are working with a USB 2.0 port and you are current limited, turn off enough DUT output voltage regulators to drop the total DUT current ≤ 470 mA. (Note: USB 2.0 ports may supply > 500 mA. Provided the nominal +5 V drops gracefully by less than 10%, the EVB will still work.) • If you are working with a USB 2.0 and you are current limited and need all output clock drivers enabled, re-configure the EVB to drive the DUT output voltage regulators from an external +5 V power supply as follows: • Connect external +5 V power supply to terminal block J33 on the back side of the PCB. • Move the jumper at JP15 from pins 1–2 USB to pins 2–3 EXT. Errata Note: The Si5348-EB REV 1.0 silkscreen at jumpers JP15-16 is reversed, i.e. the “USB” and “EXT” text are incorrectly swapped. Normal operation from USB only is still with jumpers installed between pins 1–2. This is on the right-hand side as viewed, reading the silkscreen choices. 9 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 1.0 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • January 9, 2022 9 UG511: Si5348-D Evaluation Board User's Guide • Using the Si5348-D-EVB and Installing ClockBuilder Pro Desktop Software 6.4 Overview of ClockBuilder Pro Applications Note: The following instructions and screen captures may vary slightly depending on your version of ClockBuilder Pro.

You can run a quick check to determine if the device is powered up and generating output clocks (and consuming power) by clicking on the Read All button highlighted above and then reviewing the voltage, current and power readings for each VDDx supply. Note: Shutting “Off” then “On” of the VDD and VDDA supplies will power-down and reset the DUT. Every time you do this, to reload the Skyworks-created default plan into the DUT’s register space, you must go back to the Wizard’s main menu and select “Write Design to EVB”: Figure 6.10. Write Design to EVB Failure to do the step above will cause the device to read in a preprogrammed plan from its non-volatile memory (NVM). However, the plan loaded from the NVM may not be the latest plan recommended by Skyworks for evaluation. At this point, you should verify the presence and frequencies of the output clocks (running to free-run mode from the crystal) using appropriate external instrumentation connected to the output clock SMA connectors.

Serial Device Communications (Si53848 MCU) 8.1 On-Board SPI Support The MCU onboard the Si5348-D-EVB communicates with the Si5348 device through a 4-wire SPI (Serial Peripheral Interface) link. The MCU is the SPI master and the Si5348 device is the SPI slave. The Si5348 device can also support a 2-wire I2C serial interface, although the Si5348-D-EVB does NOT support the I2C mode of operation. SPI mode was chosen for the EVB because of the relatively higher speed transfers supported by SPI vs. I2C. 8.2 External I2C Support I2C can be supported if driven from an external I2C controller. The serial interface signals between the MCU and Si5348 pass through shunts loaded on header J36. These jumper shunts must be installed in J36 for normal EVB operation using SPI with CBPro. If testing of I2C operation via external controller is desired, the shunts in J36 can be removed thereby isolating the on-board MCU from the Si5348 device. The shunt at J4 (I2C_SEL) must also be removed to select I2C as Si5348 interface type. An external I2C controller connected to the Si5348 side of J36 can then communicate to the Si5348 device. (For more information on I2C signal protocol, please refer to the Si5348 data sheet.) The figure below illustrates the J36 header schematic. J36 even numbered pins (2, 4, 6, etc.) connect to the Si5348 device and the odd numbered pins (1, 3, 5, etc.) connect to the MCU. Once the jumper shunts have been removed from J36 and J4, I2C operation should use J36 pin 4 (DUT_SDA_SDIO) as the I2C SDA and J36 pin 8 (DUT_SCLK) as the I2C SCLK. Please note the external I2C controller will need to supply its own I2C signal pull-up resistors. Figure 8.1.
