General Description

The MAX9288/MAX9290 gigabit multimedia serial link

(GMSL) deserializers receive data from a GMSL serializer

over 50Ω coax or 100Ω shielded twisted-pair (STP) cable

and output deserialized data on the CSI-2 outputs.

The MAX9290 has HDCP content protection but other-

wise is the same as the MAX9288. The deserializers pair

with any GMSL serializer capable of coax output. When

programmed for STP input, they are backward compatible

with any GMSL serializer.

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-to-UART and UART-to-I2C modes,

and up to 1Mbps in I2C-to-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 (MAX9290).

Two GPIO ports are included, allowing display power-

up and switching of the backlight, among other uses. A

continuously sampled GPI input supports touch-screen

controller interrupt requests in display applications.

For use with longer cables, the deserializers have a pro-

grammable cable equalizer. The serial input meets ISO

10605 and IEC 61000-4-2 ESD standards. The GMSL

supply is 3.0V to 3.6V, the MIPI CSI-2 supply is 1.7V to

1.9V, and the I/O supply is 1.7V to 3.6V.

The devices are available in lead(Pb)-free, 48-pin, 7mm

x 7mm TQFN and SWTQFN packages with exposed pad

and 0.5mm lead pitch.
