MAX9273GTL+

Serializers, Deserializers Overview

The MAX9273 is a 22-bit GMSL serializer designed to drive 50Ω coax or 100Ω shielded twisted-pair (STP) cable. It pairs with the MAX9272 deserializer and supports up to 1.5Gbps serial bit rates with single or double input modes, accommodating parallel clock frequencies from 6.25MHz to 100MHz. The device features an embedded control channel operating at 9.6kbps to 1Mbps in UART and mixed modes, and up to 400kbps in I²C mode. Supply voltages are 1.7V to 1.9V for the core and 1.7V to 3.6V for I/O. It operates over a temperature range of -40°C to +105°C in a 40-pin TQFN package.

Serializers, Deserializers FAQ

What types of cables can the MAX9273 drive?

The MAX9273 is designed to drive 50Ω coaxial cable or 100Ω shielded twisted-pair (STP) cable.

How does the double-input mode affect performance?

Double-input mode allows the registration of two pixels before serializing, effectively doubling the maximum pixel clock frequency compared to single-input mode.

What is the function of the embedded control channel?

The embedded control channel allows a microcontroller to program the serializer, deserializer, and peripheral registers at any time, independent of video timing, supporting UART and I²C modes.
