MAX9277
Description
The MAX9277/MAX9281 are 3.12Gbps Gigabit Multimedia Serial Link (GMSL) serializers with 3- or 4-data lane LVDS input (o LDI) and a CML serial output programmable for 50Ω coax or 100Ω shielded twisted pair (STP) cable drive. The MAX9281 has HDCP content protection but otherwise is the same as the MAX9277. The serializers pair with any GMSL deserializer capable of coax input. When programmed for STP output they are backward patible with any GMSL deserializer. The output amplitude is programmable 100m V to 500m V single-ended (coax) or 100m V to 400m V differential (STP).
The audio channel supports L-PCM I2S stereo and up to eight channels of L-PCM in TDM mode. Sample rates of 32k Hz to 192k Hz are supported with sample depth up to 32 bits.
The embedded control channel operates at 9.6kbps to 1Mbps in UART-UART and UART-I2C modes, and up to 1Mbps in I2C-I2C mode. Using the control channel, a µC can program serializer, deserializer and peripheral device registers at any time,...
