Electrical Characteristics
2.19.2
This table provides the GPIO input and output AC timing specifications.
This figure provides the AC test load for the GPIO.
2.20
The chip features a serializer/deserializer (SerDes) interface to be used for high-speed serial interconnect applications. The
SerDes interface can be used for PCI Express, Serial RapidIO, XAUI, Aurora and SGMII data transfers.
This section describes the common portion of SerDes DC electrical specifications: the DC requirement for SerDes reference
clocks. The SerDes data lane’s transmitter (Tx) and receiver (Rx) reference circuits are also shown.
2.20.1
The SerDes utilizes differential signaling to transfer data across the serial link. This section defines terms used in the description
and specification of differential signals.

GPIO inputs—minimum pulse width
Trust inputs—minimum pulse width
Note:
1. GPIO inputs and outputs are asynchronous to any visible clock. GPIO outputs should be synchronized before use by any
2. Trust inputs are asynchronous to any visible clock. Trust inputs are required to be valid for at least t
external synchronous logic. GPIO inputs are required to be valid for at least t
operation. For low power trust input pin LP_TMP_DETECT, the voltage is VDD_LP and see
requirement.
