The MAX9277/MAX9281 are 3.12Gbps Gigabit Multimedia Serial Link (GMSL) serializers with 3- or 4-data lane LVDS input (oLDI) 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 compatible with any GMSL deserializer. The output amplitude is programmable 100mV to 500mV single-ended (coax) or 100mV to 400mV differential (STP).

The audio channel supports L-PCM I2S stereo and up to eight channels of L-PCM in TDM mode. Sample rates of 32kHz to 192kHz 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, independent of video timing, and manage HDCP operation (MAX9281). A GPO output supports touch-screen controller interrupt requests from the remote end of the link.

For use with longer cables, the serializers have programmable pre/deemphasis. Programmable spread spectrum is available on the serial output. The serial output meets ISO 10605 and IEC61000-4-2 ESD standards. The core supply is 1.7 to 1.9V and the I/O supply is 1.7 to 3.6V. The package is a lead-free, 48-pin, 7mm x 7mm TQFN with exposed pad and 0.5mm lead pitch.

Product Details

The MAX9277/MAX9281 coax evaluation kits (EV kit) provide a proven design to evaluate the MAX9277 and MAX9281 high-bandwidth gigabit multimedia serial link (GMSL) serializers with spread spectrum and full-duplex control channel with the use of a standard FAKRA coaxial cable. The EV kit also includes Windows XP®-, Windows Vista®-, and Windows 7-compatible software that provides a simple graphical user interface (GUI) for exercising features of the device. The EV kit comes with a MAX9277GTM+ or MAX9281GTM+ installed.

For complete GMSL evaluation using a standard FAKRA coax cable, order the MAX9277 or MAX9281 coax EV kit and a companion deserializer board (MAX9276A or MAX9280A coax EV kit referenced in this document). For evaluating with STP cable, also order the MAXCOAX2STP-HSD adapter kit and refer to its data sheet. Only one adapter kit is required per link, connecting the serializer and deserializer (SerDes) boards.
