4.7.2. ZQSFP+

The ZQSFP+ 0/1 ports meet SFF8665 and QSFP28 industrial standards. The connector part number is Molex 170432-001. The cage part number is TE 2227103-2. The PCB trace insertion loss is less than -5 dB and return loss is less than -10 dB. The ZQSFP+ signals (Modesl, RESETL, MOdPrsl, LPmode, int) are mapped to the dedicated I/O in System MAX® 10. The BC25, BC26 pins in 2F bank are I2C interface. The user needs this interface to access ZQSFP.
