1. Description
www.DataSheet4U.com
The AT84AS008 10-bit 2.2 Gsps ADC allows accurate digitization of high frequency signals
thanks to the 3.3 GHz analog input bandwidth.
The innovative design of the on-chip Track and Hold (T/H) and digitizing core lead to unprece-
dented dynamic performance at a sampling rate of 2.2 GHz (over the full first Nyquist zone). A
7.7 ENOB is achieved at 2.2 Gps in Nyquist conditions using gray encoded digital outputs for
optimum SNR performance.
The AT84AS008 features an enhanced spectral purity and a very low noise floor, independent
on frequency and temperature. It is particularly well suited for performance enhancements (i.e.,
dithering).
The AT84AS008 is fully compatible with Atmel’s TS83102G0B 10-bit 2 Gsps ADC, allowing
zero-effort system improvement by plug-and-play replacement with the new part.

2. Functional Description
The AT84AS008 is a 10-bit 2.2 Gsps ADC. The device includes a front-end Track and Hold
stage (T/H), followed by an analog encoding stage (Analog Quantizer) which outputs analog
residues resulting from analog quantization. Successive banks of latches regenerate the analog
residues into logical levels before entering an error correction circuitry and a resynchronization
stage followed by 100differential output buffers.
The AT84AS008 works in fully differential mode from the analog inputs up to the digital outputs.
A differential Data Ready output (DR/DRB) is available to indicate when the outputs are valid
and an Asynchronous Data Ready Reset ensures that the first digitized data corresponds to the
first acquisition.
For sampling rates exceeding 2 Gsps, the gray output encoding is recommended for optimum
SNR performance.
