HDCP Gigabit Multimedia Serial Link Serializer/Deserializer

The MAX9263/MAX9264 chipset extends Maxim’s gigabit multimedia serial link (GMSL) technology to include high-bandwidth digital content protection (HDCP) encryption of video and audio data. The MAX9263 serializer, or any HDCP-GMSL serializer, pairs with the MAX9264 deserializer, or any HDCP-GMSL deserializer, for the transmission of control data and HDCP encrypted video and audio data.

The parallel interface operates with a pixel clock up to 104MHz. Three inputs are for I2S audio, supporting a sampling frequency to 192kHz and a sample depth to 32 bits. The embedded control channel forms a fullduplex differential 9.6kbps to 1Mbps UART link between the serializer and deserializer. A microcontroller (µC), can be located on the serializer side of the link, on the deserializer side of the link, or on both sides. The control channel enables µC control of peripherals on the remote side, such as backlight control, touch screen, and perform HDCP-related operations.

For driving longer cables, the serializer has programmable pre/deemphasis, and the deserializer has a programmable channel equalizer. The GMSL devices have programmable spread spectrum on the serial (serializer) and parallel (deserializer) output. The serial link input and output meet ISO 10605 and IEC 61000-4-2 ESD standards. The serializer core supply is 1.8V and the deserializer core supply is 3.3V. The I/O supply is 1.8V to 3.3V. Both devices are available in a 64-pin TQFP package with an exposed pad and are specified over the -40°C to +105°C automotive temperature range.
