It is function and pin compatible with the MAX9271. In high- bandwidth mode, the parallel-clock maximum is 116MHz for 12-bit linear or combined HDR data types. The embedded control channel operates at 9.6kbps to 1Mbps in UART, I2C, and mixed UART/I2C modes, allow- ing programming of serializer, deserializer, and camera registers independent of video timing. For driving longer cables, the IC has programmable pre/deemphasis. Programmable spread spectrum is available on the serial output. The serial output meets ISO 10605 and IEC 61000-4-2 ESD standards. The core supply range is 1.7V to 1.9V, and the I/O supply range is 1.7V to 3.6V. The MAX96705 is available in a 32-pin (5mm x 5mm) TQFN package with 0.5mm lead pitch, and operates over the -40°C to +115°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Package Information For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”, “#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. 32-Pin TQFN-EP Package Code Outline Number Land Pattern Number Single-Layer Board: T3255+8 21-0140 90-0013 Junction-to-Ambient Thermal Resistance (θJA) Junction-to-Case Thermal Resistance (θJC) Four-Layer Board: Junction-to-Ambient Thermal Resistance (θJA) Junction-to-Case Thermal Resistance (θJC) 47 1.7 29 1.7 Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
