MAX9273GTL+

MAX9273GTL+ is a 22-bit GMSL serializer with a coax or STP cable drive. This compact serializer is designed to drive 50I coax or 100I shielded twisted-pair (STP) cable. The device pairs with the MAX9272 deserializer. The parallel input is programmable for single or double input. Double input allows higher pixel clock input frequency by registering two pixels of typical image-sensor video data before serializing. This doubles the maximum pixel clock frequency compared to single input. This device features an embedded control channel that operates at 9.6Kbps to 1Mbps in UART and mixed UART/ I²C modes, and up to 400Kbps in I²C mode. Using the control channel, a microcontroller (FC) is capable of programming serializer, deserializer, and camera (or any peripheral) registers at any time, independent of video timing. It is used in applications such as automotive camera systems, and navigation displays.

• Error detection/correction, best-in-class supply current is 75mA maximum
• programmable spread spectrum on the serial output reduces EMI
• Bypassable input PLL for parallel clock jitter attenuation
• Tracks spread spectrum on parallel input, up to five GPIO ports
• Remote/local wake-up from sleep mode
• ±8kV contact and ±15kV air ISO 10605 and IEC 61000-4-2 ESD protection
• Sleep mode supply current is 40µA maximum at (single wake-up receiver enabled)
• Clock frequency range from 6.25 to 12.5MHz at (BWS = 1, DRS = 1, TA = +25°C)
• Clock duty cycle is 50% typical at (VDVDD = VAVDD = 1.7V to 1.9V)
• Operating temperature range from -40°C to +105°C, 40-pin TQFN-EP package
