DescripTion

Quad 14-Bit, 125Msps ADC

with Integrated Drivers

integrated, fixed gain, differential ADC drivers. The low

noise amplifiers are suitable for single-ended drive and

pulse train signals such as imaging applications. Each

channel includes a lowpass filter between the driver out-

put and ADC input.

DC specs include ±1.2LSB INL (typ), ±0.3LSB DNL (typ)

and no missing codes over temperature. The transition

The digital outputs are serial LVDS and each channel out-

puts two bits at a time (2-lane mode). At lower sampling

rates there is a one bit option (1-lane mode). The LVDS

drivers have optional internal termination and adjustable

output levels to ensure clean signal integrity.

or single-ended with a sine wave, PECL, LVDS, TTL or

CMOS inputs. An internal clock duty cycle stabilizer al-

lows high performance at full speed for a wide range of

clock duty cycles.
