Rainbow Electronics MAX109 - Manual

General Description
The MAX109, 2.2Gsps, 8-bit, analog-to-digital converter
(ADC) enables the accurate digitizing of analog signals
with frequencies up to 2.5GHz. Fabricated on an
advanced SiGe process, the MAX109 integrates a high-
performance track/hold (T/H) amplifier, a quantizer, and
a 1:4 demultiplexer on a single monolithic die. The
MAX109 also features adjustable offset, full-scale volt-
age (via REFIN), and sampling instance allowing multi-
ple ADCs to be interleaved in time.
The innovative design of the internal T/H amplifier,
which has a wide 2.8GHz full-power bandwidth,
enables a flat-frequency response through the second
Nyquist region. This results in excellent ENOB perfor-
mance of 6.9 bits. A fully differential comparator design
and decoding circuitry reduce out-of-sequence code
errors (thermometer bubbles or sparkle codes) and
provide excellent metastability performance (10
14 clock
cycles). This design guarantees no missing codes.
The analog input is designed for both differential and
single-ended use with a 500mV
P-P input-voltage range.
The output data is in standard LVDS format, and is
demultiplexed by an internal 1:4 demultiplexer. The
LVDS outputs operate from a supply-voltage range of
3V to 3.6V for compatibility with single 3V-reference
systems. Control inputs are provided for interleaving
additional MAX109 devices to increase the effective
system-sampling rate.
The MAX109 is offered in a 256-pin Super Ball-Grid Array
(SBGA) package and is specified over the extended
industrial temperature range (-40°C to +85°C).
