LTC2207/LTC2206

16-Bit, 105Msps/80Msps

ADCs

DESCRIPTIO

The LTC

2207/LTC2206 are 105Msps/80Msps, sampling

16-bit A/D converters designed for digitizing high fre-

quency, wide dynamic range signals up to input frequencies

of 700MHz. The input range of the ADC can be optimized

with the PGA front end.

The LTC2207/LTC2206 are perfect for demanding commu-

nications applications, with AC performance that includes

78.2dB Noise Floor and 100dB spurious free dynamic range

(SFDR). Ultralow jitter of 80fs

RMS

allows undersampling of

high input frequencies with excellent noise performance.

Maximum DC specs include ±4LSB INL, ±1LSB DNL (no

missing codes) over temperature.

A separate output power supply allows the CMOS output

swing to range from 0.5V to 3.6V.

The ENC

and ENC

–

inputs may be driven differentially

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

CMOS inputs. An optional clock duty cycle stabilizer al-

lows high performance at full speed with a wide range of

clock duty cycles.
