MAX9240AGTM/V+ Analog Devices

EVALUATION KIT AVAILABLE MAX9240A 6.25MHz to 100MHz, 25-Bit GMSL Deserializer for Coax or STP Cable with Line Fault Detect General Description Benefits and Features The MAX9240A compact deserializer is designed to Ideal for Camera Applications interface with a GMSL serializer over 50 coax or 100 Works with Low-Cost 50 Coax Cable and FAKRA shielded twisted-pair (STP) cable. The device pairs with Connectors or 100 STP the MAX9271 or MAX9273 serializers. Error Detection/Correction 2 2 9.6kbps to 1Mbps Control Channel in I C-to-I C The parallel output is programmable for single or double Mode with Clock Stretch Capability output. Double output strobes out half of a parallel word Best-in-Class Supply Current: 90mA (max) on each pixel clock cycle. Double output can be used with Double-Rate Clock for Megapixel Cameras GMSL serializers that have the double-input feature. Cable Equalization Allows 15m Cable at Full Speed The device features an embedded control channel that 48-Pin (7mm x 7mm) TQFN-EP Package with operates at 9.6kbps to 1Mbps. Using the control chan- 0.5mm Lead Pitch nel, a microcontroller (C) can program the serializer/ High-Speed Data Deserialization for Megapixel deserializer and peripheral device registers at any time, Cameras independent of video timing. Two programmable GPIO Up to 1.5Gbps Serial-Bit Rate with Single or ports and a continuously sampled GPI input are available. Double Output: 6.25MHz to 100MHz Clock For use with longer cables, the device has a program- Multiple Control-Channel Modes for System Flexibility mable equalizer. Programmable spread spectrum is avail- 9.6kbps to 1Mbps Control Channel in UART-to- able on the parallel output. The serial input meets ISO 2 UART or UART-to-I C Modes 10605 and IEC 61000-4-2 ESD standards. The core sup- ply range is 1.7V to 1.9V and the I/O supply range is 1.7V Reduces EMI and Shielding Requirements to 3.6V. The device is available in a 48-pin (7mm x 7mm) Programmable Spread Spectrum on the Parallel TQFN-EP package with 0.5mm lead pitch and operates Output Reduces EMI over the -40C to +105C temperature range. Tracks Spread Spectrum on Serial Input Peripheral Features for Camera Power-Up and Applications Verification Automotive Camera Systems Built-In PRBS Checker for BER Testing of the Serial Link Fault Detection of Serial Link Shorted Together, to Ground, to Battery, or Open Two GPIO Ports Dedicated Up/Down GPI for Camera Frame Sync Trigger and Other Uses Ordering Information appears at end of data sheet.
