Qsfp56 Module Pad Layout; Control Signals (Osfp) - Nvidia MFA7U10-H00 Series Manual

2.2.1 QSFP56 Module Pad Layout

2.3 Control Signals (OSFP)

This AOC has CMIS 4.0 (check for update, e.g. to CMIS 5) compliant management interface and OSFP
4.1 (check for update) compliant form factor and interfaces. This implies that the control signals
shown in the pad layout are implemented with the following functions:

Description
Multi-level signal for low power control from host to
module and module presence indication from module to
host. This signal requires the circuit as described in the
OSFP Specification [ ].
Multi-level signal for interrupt request from module to
host and reset control from host to module. This signal
requires the circuit as described in the OSFP
Specification [ ].
2-wire serial clock signal. Requires pull-up resistor to
3.3V on host.
2-wire serial data signal. Requires pull-up resistor to
3.3V on host.
