EVALUATION KIT AVAILABLE MAX9273 22-Bit GMSL Serializer with Coax or STP Cable Drive General Description Benefits and Features S Ideal for Camera Applications The MAX9273 compact serializer is designed to drive 50I coax or 100I shielded twisted-pair (STP) cable. Drives Low-Cost 50I Coax Cable and FAKRA The device pairs with the MAX9272 deserializer. The Connectors or 100I STP parallel input is programmable for single or double input. Error Detection/Correction 2 2 Double input allows higher pixel clock input frequency by 9.6kbps to 1Mbps Control Channel in I C-to-I C registering two pixels of typical image-sensor video data Mode with Clock Stretch Capability before serializing. This doubles the maximum pixel clock Best-in-Class Supply Current: 75mA (max) frequency compared to single input. Double-Rate Clock for Megapixel Cameras Serializer Pre/Deemphasis Allows 15m Cable at The device features an embedded control channel that Full Speed operates at 9.6kbps to 1Mbps in UART and mixed UART/ 40-Pin (6mm x 6mm) TQFN Package with 0.5mm 2 2 I C modes, and up to 400kbps in I C mode. Using the Lead Pitch control channel, a microcontroller (FC) is capable of S High-Speed Data Serialization for Megapixel programming serializer, deserializer, and camera (or any Cameras peripheral) registers at any time, independent of video timing. There is one dedicated GPIO, four optional GPIOs, Up to 1.5Gbps Serial-Bit Rate with Single or Double Input: 6.25MHz to 100MHz Clock and a GPO output, allowing remote power-up of a camera module, camera frame synchronization, and other uses. S Multiple Control-Channel Modes for System Error-detection and correction coding are programmable. Flexibility For driving longer cables, the serializer has program- 9.6kbps to 1Mbps Control Channel in UART-to- 2 mable pre/deemphasis. Programmable spread spectrum UART or UART-to-I C Modes is available on the serial output. The serial output meets S Reduces EMI and Shielding Requirements ISO 10605 and IEC 61000-4-2 ESD standards. The core Output Programmable for 100mV to 500mV supply range is 1.7V to 1.9V and the I/O supply range is Single-Ended or 100mV to 400mV Differential 1.7V to 3.6V. The device is available in a 40-pin (6mm x Programmable Spread Spectrum on the Serial 6mm) TQFN-EP package with 0.5mm lead pitch and oper- Output Reduces EMI ates over the -40NC to +105NC temperature range.
