The MAX9247 is a MAXIM digital video parallel-to-serial converter that supports the conversion of 27-bit parallel data to serial data. It supports the encoding and multiplexing of 18-bit video data and 9-bit control data onto the serial interface, reducing the serial data rate. The MAX9247 pairs with the MAX9248/MAX9250 deserializers to form a complete digital video serial link.
The MAX9247 is a digital video parallel‑to‑serial converter that serializes 27 bits of parallel data (18 video bits and 9 control bits) into a LVDS serial stream. It operates from a +3.3 V core supply and uses a separate input supply for 1.8 V‑to‑3.3 V logic levels, making it suitable for navigation displays, in‑vehicle entertainment, video cameras, and LCDs.
Key features include a 48‑lead LQFP package, operation from –40 °C to +105 °C, integrated 100 Ω LVDS termination, pre‑emphasis for improved eye diagrams, and robust ESD protection (±10 kV contact, ±30 kV air‑gap). The device supports clock frequencies from 2.5 MHz to 42 MHz and provides programmable phase‑shifted LVDS signaling.
