The Atmel TS81102G0 a single-chip demultiplexer (DMUX) for A/D conversion and DMUX combinations used in telecommunications, industrial and military applications.

The TS81102G0 offers high capacity and high speed, with 8 or 10bit data flow processed at speeds of up to 2Gsample/s, as well as the flexibility of two programmable demultiplexing ratios and compatibility with a wide variety of ADCs.

This provides an ideal solution for users requiring control of processor high-speed data feeds.

The DMUX complements Atmel's high-performance 8bit 1Gsample/s TS8388B, 10bit 2Gsample/s TS83102G0 and 8bit 4Gsample/s TS83084G0 ADCs, and is based on advanced high-speed technology.

It provides two programmable DMUX ratios of 1:4 and 1:8, with maximum datarates of 1 and 2Gsample/s, respectively.

The input clock can be set up to produce an ECL differential signal or single-ended DC coupled signal and can be used as a data ready or data ready/2 input clock.

Input clock sampling is delay adjustable.

Available in a 240-pin tape ball grid array (TBGA) package, the device's input digital data comprises ECL differential signals.

The device supports parallel output.

Its output signals - data ready, digital data and reference voltage - are all adjustable.

The data ready output is differential, digital output data and reference voltages are single-ended signals.

Typical output modes are ECL, PECL or TTL.

Fine tuning of the output swing is also available.

The TS81102G0 is started by an asynchronous reset.

A synchronous reset enables re-synchronisation of the output port and minimises possible loss of data that could occur within the DMUX.

A built-in self-test is included in the device.

The TS81102G0 is available in industrial, 0 to 90C, and military, -40 to +110C, temperature ranges and has a radiation tolerance of more than 100krad.
