IEEE Analog Test Pins
Differential outputs providing reference clocks for IEEE PHY
conformance verification. For prototype testing, connect each pair to
two-pin headers. For production systems, leave pins unconnected.
Thermal Diode Reference
Can be used to measure the slicon device temperature.
Factory Test Pin
Attach a 1 KΩ pull-down resistor to ground for normal operation.
SERDES Receive Pairs
Signals SRDSI_0_PLUS and SRDSI_0_MINUS make the differential
receive pair for the 1.25 GHz serial interface for Port 0. Inputs
should be PICMIG 3.1-compliant.
Signals SRDSI_1_PLUS and SRDSI_1_MINUS make the differential
receive pair for the 1.25 GHz serial interface for Port 1. Inputs
should be PICMIG 3.1-compliant.
If the SERDES interface is not used, these pins should not be
connected.
SERDES Transmit Pairs
Signals SRDSO_0_PLUS and SRDSO_0_MINUS make the
differential transmit pair for the 1.25 GHz serial interface for Port 0.
Outputs drive PICMIG 3.1-compliant signals.
Signals SRDSO_1_PLUS and SRDSO_1_MINUS make the
differential transmit pair for the 1.25 GHz serial interface for Port 1.
Outputs drive PICMIG 3.1-compliant signals.
If the SERDES interface is not used, these pins should not be
connected.
Signal Detects
These pins (SRDSA_SIG_DET for Port 0; SRDSB_SIG_DET for Port
1) indicate whether the SERDES signals (connected to the 1.25 GHz
serial interface) have been detected by the optical transceivers. If
the SERDES interface is not used, the SIG_DET inputs can be left
unconnected.
SERDES Impedance Compensation.
Connect the recommended resistor value across these balls, even if
not using the SERDES interface. Refer to the 82571EB/82572EI
Design Guide for the recommended value.
