Measured with conformance test signal at BER=1×10⁻¹². 5. Vertical eye closure penalty and stressed eye jitter are test conditions for stressed receiver sensitivity.
Pin Description
Figure 2. Electrical Pin-out Details
ModSelL Pin
The ModSelL is an input signal pulled to Vcc in the QSFP-DD module. When held low by the host, the module responds to 2-wire serial communication commands. Allows multiple QSFP-DD modules on a single 2-wire interface bus.
ResetL Pin
The ResetL signal is pulled to Vcc in the module. A low level for longer than the minimum pulse length initiates a complete module reset, returning all user settings to default state.
LPMode Pin
LPMode is an input signal pulled up to Vcc in the QSFP-DD module. Used in the control of module power mode (See CMIS Section 6.3.1.3).
ModPrsL Pin
ModPrsL is pulled up to Vcc on the host board and grounded in the module. Asserted “Low” when module is inserted, deasserted “High” when physically absent.
IntL Pin
IntL is an open collector output, pulled to Vcc on the host board. When asserted Low, it indicates a change in module state, a possible operational fault, or a status critical to the host system.
Power Supply Filtering
The host board should use the power supply filtering shown below.
Figure 3. Host Board Power Supply Filtering
Diagnostic Monitoring Interface
Digital diagnostics monitoring is available on all F-tone Networks QSFP DD products. A 2-wire serial interface provides user contact with the module. The CMIS Memory Map defines serial ID, digital monitoring, and control functions.
The memory space is arranged into a lower single-page address space of 128 bytes and multiple upper address space pages. This structure supports a flat 256 byte memory for passive copper cables and permits timely access to addresses in the lower page (Flags and Monitors). Less time critical entries (serial ID, threshold settings) use the Page Select function.
