4.11.15.1 PCIE_REXT Reference Resistor Connection

The impedance calibration process requires connection of reference resistor 200

Ω. 1% precision resistor

on PCIE_REXT pads to ground. It is used for termination impedance calibration.

4.11.16 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.

Figure 84 depicts the timing of the PWM, and Table 78 lists the PWM timing parameters.
