FPC402: FPC pin Function

Dilip Namdeo Mohol
Intellectual 2040 points
Part Number: FPC402


Would like to double check whether we can use one FPC402 with following pin functions for 4 QSFP/QSFP-DD:

QSFP_PWR_EN_L - Output (GPIO0/1/2/3) à Power enable for HSWAP/circuit protector

QSFP_RESET_L - Output  (OUT_A)

QSFP_LPMODE - Output (OUT_B)

QSFP_LED_G - Output (OUT_C)

QSFP_LED_R - Output (OUT_D)

 

QSFP_PWR_PG_L - Input (IN_C) à Power Good from HSWAP/Circuit Protector

QSFP_INT_L - Input  (IN_B)

QSFP_PRESENT_L - Input (IN_A)

    Hi Dilip,

    FPC402 support 2 LED drivers with advanced control such as dimming(these could be used for LED OUT_C &OUT_D). Additionally it supports 6 GPIO as well for other functions you noted. Given this limitation, I believe FPC402 can meet the requirement you noted.
