Figure 38. PCIE_REXT reference resistor connection

NOTE

The validation of the PCIe interface was performed with 845

Ohm to match the 85 Ohm differential impedance of the

PCB traces. Other values may be used on boards designed

for other impedances.

3.10.7.2 PCIE_REF_CLK

Please refer to the Hardware Developers Guide for this device, which contains details

on the PCIe reference clock requirements.

3.10.8 Pulse Width Modulator (PWM) Timing Parameters

This section describes the electrical information of the PWM. The PWM can be

programmed to select one of three clock signals as its source frequency. The selected

clock signal is passed through a prescaler before being input to the counter. The

output is available at the pulse-width modulator output (PWMO) external pin.

The following figure depicts the timing of the PWM, and Table 64 lists the PWM

timing parameters.
