The MAX9220EUM+TD (MAX9220) is a family of serializers, deserializers (SerDes) designed for high speed, low latency, uncompensated data acquisition applications in the instrumentation, test and automation industries. The device operates from a single 3.3-V supply and can provide up to 24-bit resolution at speeds up to 25 MHz. MAX9220 devices are well suited for tachometers, resolvers, current transducers, rotary encoders, strain gauge bridges, and distance measurement applications.

The MAX9220 family of SerDes devices is based on Inmos’s innovative Transistor-Controlled-Coupled (TCC) technology and enables unprecedented levels of integration and cost savings for high-speed data acquisition applications. The device comprises six independent differential channels: four outputs, an input, and an enable input. The output channels provide fast, ultra-low-jitter, 8-bit to 24-bit words (at 25 MHz or lower) in parallel format.

The MAX9220 SerDes devices feature the revolutionary TCC output technology which provides the desired performance without any additional receiver deskew circuitry or time-domain equalization. The outputs are logically shifted (phase-shifted) such that a predetermined output differential pair will be together, no matter how long the clock-to-data transmission is. This makes the device compatible with clock and data skew.

The input channel of the MAX9220 SerDes devices includes an optional source-synchronous data strobe and supports data rate up to 10 MHz. The input channel can be configured as either dc-coupled or ac-coupled operation. The input filter frequency and slew rate can be programmed to accommodate different incoming data sources and output requirements.

The MAX9220 SerDes devices are also integrated with adjustable phase detect logic and a selective programmable phase control. The phase control feature enables the device to automatically adjust word phase and data phase relative to the clock, leading to better system performance in high-data-rate, low-cost solutions.

The MAX9220 SerDes devices have an integrated post-amplification output driver to ensure optimal signal integrity at high data rates. The output drivers can be programmed for 2.5-V, 1.65-V, 1.8-V and 1.2-V logic levels, making them suitable for a wide range of output voltage requirements.

The MAX9220 SerDes devices are available in different packages to meet various system requirements. In addition to the usual 16- and 24-pin packages, customers can also opt for an 8-pin package which provides two separate 5-bit outputs.

The MAX9220 SerDes devices have been designed for ease of implementation and debugging. They include several control and diagnostic features such as strobing and parity, error record and input/output buffering. The devices also include a flexible programming interface to enable fast prototyping and integration into any application.

In conclusion, the MAX9220 SerDes family provides an ideal solution for high-speed and low-latency data acquisition applications. They are well suited for tachometers, resolvers, current transducers, rotary encoders, strain gauge bridges, and distance measurement applications. With their flexible programming interface, high-speed output data rates, and exceptional signal integrity, the MAX9220 SerDes devices are an excellent choice for system designers.
