The MAX9263/MAX9264 chipset extends Maxim's gigabit multimedia serial link (GMSL) technology to include high-bandwidth digital content protection (HDCP) encryption for content protection of DVD and Blu-ray™ video and audio data. The MAX9263 serializer, or any HDCP-GMSL serializer, pairs with the MAX9264 deserializer, or any HDCP-GMSL deserializer, to form a digital serial link for the transmission of control data and HDCP encrypted video and audio data. GMSL is an HDCP technology approved protocol by Digital Content Protection (DCP), LLC.
The parallel interface is programmable for 24-bit or 32-bit width and operates with a pixel clock of 8.33MHz to 104MHz (24 bit) or 6.25MHz to 78MHz (32 bit). When programmed for 24-bit or 32-bit width, three inputs are for I²S audio, supporting a sampling frequency from 8kHz to 192kHz and a sample depth of 4 bits to 32 bits. The embedded control channel forms a full-duplex differential 9.6kbps to 1Mbps UART link between the serializer and deserializer. An electronic control unit (ECU), or microcontroller (µC), can be located on the serializer side of the link (typical for video display), on the deserializer side of the link (typical for image sensing), or on both sides (typical for HDCP video display repeaters). The control channel enables ECU/µC control of peripherals on the remote side, such as backlight control, touch screen, and perform HDCP-related operations.
The serial link signaling is AC-coupled CML with 8b/10b coding. 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.
