User Manual VersaClock 3S - 5P35023 Evaluation Board Introduction The evaluation board is designed to help the customer evaluate the 5P35023 device, the latest addition to the family of programmable devices in IDT s Timing portfolio. When the board is connected to a PC running IDT Timing Commander software through a USB, the device can be configured and programmed to generate different combinations of frequencies. Board Overview Use Figure 1 and Table 1 to identify: USB connector and the input and output frequency SMA connectors. Figure 1.

Evaluation Board Labels and Functions Label On-board Connector Name Function Number Label This is used to set outputs enable/disable on the IC and switches DFC 1 DIP Switch SW1 in different configurations. 2 Reference Output REF This is the reference or buffered output from the crystal. Differential Clock Input CLKIN/CLKINB A differential clock can be connected as source for the device. 3 A Single-ended clock can be connected as source for the device using Single-ended Clock Input CLKINB CLKINB only. 4 Crystal, 25MHz This crystal is used as a reference source for the clock signal. 5 USB Connector J3 Connect this USB to your PC to run IDT Timing Commander. This can be a differential pair, or two single-ended outputs. By default, A Differential Output 2 DIFF T2/C2 its an LPHCSL differential output. B Output-enable Connector OE3 This port can be used in Pro-active Power Saving (PPS) mode. This is the single-ended output. By default its an LVCMOS C Single-ended Output SE 3 single-ended output. This can be a differential pair, or two single-ended outputs. By default, D Differential Output 1 DIFF T1/C1 its LPHCSL differential output. E Output-enable Connector SMA OE1 This port can be used in Pro-active Power Saving (PPS) mode. This is the single-ended output. By default its an LVCMOS F Single-ended Output SE 1 single-ended output. This is the single-ended output. By default its an LVCMOS G Single-ended Output SE 2 single-ended output. H Output enable Connector OE2 This port can be used in Pro-active Power Saving (PPS) mode. This is a four-way header used to select an output voltage. Connect I Output Voltage Selector E1, E2, E3, E4, E5 center pin to GND, and then the respective voltage (3.3V as default). J Input Selector JP5, JP6 This is used to configure input from USB or external power supply. Board Power Supply Power Supply Options The core voltage includes a digital voltage V and an analog voltage V . Both core voltages can be powered by USB as default. DD33 DDA USB Power Supply only When the board is connected to a PC through a USB cable, on-board voltage regulators will generate a 3.3V for the device. In this case, place the jumper as shown in Figure 2. See the JP5 jumper position for the on-board voltage regulators in the following figure. USB power source is recommended because it s readily available right from your laptop. 2017 Integrated Device Technology, Inc. 2 June 8, 2017
