General Description

The MAX9275/MAX9279 are 3.12Gbps Gigabit Multimedia Serial Link (GMSL) serializers with parallel LVCMOS inputs and a CML serial output programmable for 50Ω coax or 100Ω shielded twisted pair (STP) cable drive. The MAX9279 has HDCP content protection but otherwise is the same as the MAX9275. The serializers pair with any GMSL deserializer capable of coax input. When programmed for STP output they are backward compatible with any GMSL deserializer. The output amplitude is programmable 100mV to 500mV, single-ended (coax) or 100mV to 400mV differential (STP).
