EVALUATION KIT AVAILABLE MAX9272A 28-Bit GMSL Deserializer for Coax or STP Cable General Description Benefits and Features The MAX9272A 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 shielded twisted-pair (STP) cable. The device pairs with FAKRA 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 output. Double output strobes out half of a parallel word Mode with Clock-Stretch Capability Best-in-Class Supply Current: 90mA (max) on each pixel clock cycle. Double output can be used with GMSL serializers that have the double-input feature. Double-Rate Clock for Megapixel Cameras Cable Equalization Allows 15m Cable at Full The device features an embedded control channel that Speed operates at 9.6kbps to 1Mbps. Using the control chan- 48-Pin (7mm x 7mm) TQFN-EP Package with nel, a microcontroller (C) can program the serializer/ 0.5mm Lead Pitch deserializer and peripheral device registers at any time, High-Speed Data Deserialization for Megapixel independent of video timing. Two programmable GPIO Cameras ports and a continuously sampled GPI input are available. Up to 1.5Gbps Serial-Bit Rate with Single or For use with longer cables, the device has a program- Double Output: 6.25MHz to 100MHz Clock mable equalizer. Programmable spread spectrum is avail- Multiple Control-Channel Modes for System Flexibility able on the parallel output. The serial input meets ISO 9.6kbps to 1Mbps Control Channel in UART-to- 10605 and IEC 61000-4-2 ESD standards. The core sup- 2 UART or UART-to-I C Modes 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) TQFN-EP package with 0.5mm lead pitch and operates Input Programmable for 100mV to 500mV over the -40C to +105C temperature range. Single-Ended or 50mV to 400mV Differential Programmable Spread Spectrum on the Parallel Applications Output Reduces EMI Automotive Camera Systems Tracks Spread Spectrum on Serial Input Peripheral Features for Camera Power-Up and Verification Built-In PRBS Checker for BER Testing of the Serial Link Two GPIO Ports Dedicated Up/Down GPI for Camera Frame Sync Trigger and Other Uses Remote/Local Wake-Up from Sleep Mode Meets Rigorous Automotive and Industrial Requirements -40C to +105C Operating Temperature Ordering Information appears at end of data sheet. 10kV Contact and 15kV Air IEC 61000-4-2 ESD Protection Typical Application Circuit appears at end of data sheet. 10kV Contact and 30kV Air ISO 10605 ESD Protection For related parts and recommended products to use with this part, refer to www.maximintegrated.com/MAX9272A.related. 19-7404 Rev 0 5/14MAX9272A 28-Bit GMSL Deserializer for Coax or STP Cable TABLE OF CONTENTS General Description ............................................................................ 1 Applications .................................................................................. 1 Benefits and Features .......................................................................... 1 Absolute Maximum Ratings* ..................................................................... 6 Package Thermal Characteristics (Note 1) .......................................................... 6 DC Electrical Characteristics ..................................................................... 6 AC Electrical Characteristics . 8 Typical Operating Characteristics ................................................................ 10 Pin Configuration ............................................................................. 12 Pin Description ............................................................................... 12 Functional Diagram ........................................................................... 14 Detailed Description........................................................................... 18 Register Mapping . 18 Bit Map . 18 Serial Link Signaling and Data Format . 24 Reverse Control Channel . 24 Data-Rate Selection . 24 Control Channel and Register Programming . 25 UART Interface . 25 Interfacing Command-Byte-Only 2 I C Devices with UART 26 UART Bypass Mode 26 2 I C Interface . 26 START and STOP Conditions . 28 Bit Transfer 28 Acknowledge 28 Slave Address . 29 Bus Reset . 29 Format for Writing 29 Format for Reading . 29 2 I C Communication with Remote-Side Devices . 30 2 I C Address Translation 30 Control-Channel Broadcast Mode 30 GPO/GPI Control . 30 PRBS Test . 31 Line Equalizer 31 Maxim Integrated 2 www.maximintegrated.com
