Maxim MAX9240A 25-Bit GMSL Deserializer

Maxim MAX9240A 25-Bit GMSL Deserializer

Maxim MAX9240A 25-Bit Compact Deserializer is designed to interface with a GMSL serializer over 50Ω coax or 100Ω shielded twisted-pair (STP) cable. This Maxim device pairs with MAX9271 or MAX9273 serializers. The parallel output of is programmable for single or double output. Double output strobes out half of a parallel word on each pixel clock cycle. Double output can be used with GMSL serializers that have the double-input feature. MAX9240A features an embedded control channel that operates at 9.6kbps to 1Mbps. Using the control channel, a microcontroller can program the serializer/deserializer and peripheral device registers at any time, independent of video timing. Two programmable GPIO ports and a continuously sampled GPI input are available. For use with longer cables, the device has a programmable equalizer. Programmable spread spectrum is available on the parallel output. The serial input meets ISO 10605 and IEC 61000-4-2 ESD standards. The core supply range is 1.7V to 1.9V and the I/O supply range is 1.7V to 3.6V. The device operates over a -40°C to +105°C temperature range.
