Octal, 12-Bit, 40Msps, 1.8V ADC with Serial LVDS Outputs

Product Details

The MAX1436 octal, 12-bit analog-to-digital converter (ADC) features fully differential inputs, a pipelined architecture, and digital error correction incorporating a fully differential signal path. This ADC is optimized for low-power and high-dynamic performance in medical imaging instrumentation and digital communications applications. The MAX1436 operates from a 1.8V single supply and consumes only 743mW (93mW per channel) while delivering a 69.9dB (typ) signal-to-noise ratio (SNR) at a 5.3MHz input frequency. In addition to low operating power, the MAX1436 features a power-down mode for idle periods.

An internal 1.24V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of an external reference for applications requiring increased accuracy or a different input voltage range. The reference architecture is optimized for low noise.

A single-ended clock controls the data-conversion process. An internal duty-cycle equalizer compensates for wide variations in clock duty cycle. An on-chip PLL generates the high-speed serial low-voltage differential signal (LVDS) clock.

The MAX1436 has self-aligned serial LVDS outputs for data, clock, and frame-alignment signals. The output data is presented in two's complement or binary format.

The MAX1436 offers a maximum sample rate of 40Msps. See the Pin-Compatible Versions table in the full data sheet for higher-speed versions. This device is available in a small, 14mm x 14mm x 1mm, 100-pin TQFP package with exposed pad and is specified for the extended industrial (-40°C to +85°C) temperature range.

Description

The MAX1434/MAX1436/MAX1437/MAX1438 evaluation kits (EV kits) are fully assembled and tested circuit boards that contain all the components necessary to evaluate the performance of this family of octal 10-/12-bit analog-to-digital converters (ADCs). These ADCs accept differential analog input signals. The EV kits generate these signals from user-provided single-ended input sources. The EV kits' digital outputs can be easily sampled with a user-provided high-speed logic analyzer or data-acquisition system. The EV kits also feature an on-board deserializer to simplify integration with standard logic analysis systems. The EV kits operate from 1.8V and 3.3V (plus 1.5V if the FPGA is used) power supplies and include circuitry that generates a clock signal from an AC signal provided by the user.
