Preliminary Data Sheet

PCI Express Interface (n = 0 and 1)

PCIEnATB

Analog Test Bus for manufacturing test.

CML

PCIEnClkC

PCIEnClkT

Differential input for external reference clock.

CML

PCIEnRExt

PCIEnRExtG

External reference resistor. Attach a 1.37 k

Ω, 1% resistor between

RExt and RExtG to provide the reference for both the bias currents

and the impedance calibration circuitry.

Notes:

1. Receiver input has hysteresis.

2. Must pull up. See “Pull-Up and Pull-Down Resistors” on page 37 for recommended termination values.

3. Must pull down. See “Pull-Up and Pull-Down Resistors” on page 37 for recommended termination values.

4. If not used, must pull up.

5. If not used, must pull down.

6. Strapping input during reset; pull up or pull down as required.
