MAX9278AGTM+

MAX9278AGTM+ is a 3.12Gbps GMSL deserializer for coax or STP input and LVDS output. This gigabit multimedia serial link (GMSL) deserializer receives data from a GMSL serializer over 50 ohm coax or 100 ohm shielded twisted-pair (STP) cable and outputs deserialized data on 3 of 4 data-lane LVDS outputs (oLDI). 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. Two GPIO ports are included, allowing display powerup and switching of the backlight among other uses. A continuously sampled GPI input supports touch-screen controller interrupt requests in display applications. The serial input and LVDS output meet ISO 10605 and IEC 61000-4-2 ESD standards. The core supply is 3V to 3.6V and the I/O supply is 1.7V to 3.6V. It is used in applications such as high-resolution automotive navigation, rear-seat infotainment, and megapixel camera systems.

• ±8kV contact and ±15kV air ISO 10605 and IEC 61000-4-2 ESD protection
• Remote/local wake-up from sleep mode, two dedicated GPIO ports
• Built-in PRBS tester for BER testing of the serial link
• High-immunity mode for maximum control channel noise rejection
• Programmable spread spectrum reduces EMI, tracks spread spectrum on input
• Colour lookup table for gamma correction, CNTL[3:0] control outputs
• Audio clock from audio source or audio sink, equalization allows 15m cable at full speed
• 104MHz high-bandwidth mode supports 1920 x 720p/60Hz display with 24-bit colour
• Single-ended input current is +20µA maximum at (VAVDD = VDVDD = 3.0V to 3.6V)
• Operating temperature range from -40°C to +105°C, 48-pin TQFN-EP package
