LTC2208-14

14-Bit, 130Msps ADC

FEATURES

DESCRIPTIO

■

Sample Rate: 130Msps

The LTC^®2208-14 is a 130Msps, sampling 14-bit A/D

converter designed for digitizing high frequency, wide

dynamic range signals with input frequencies up to

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

with the PGA front end.

TheLTC2208-14isperfectfordemandingcommunications

applications,withACperformancethatincludes77.1dBFS

NoiseFloorand98dBspuriousfreedynamicrange(SFDR).

Ultralow jitter of 70fs

allows undersampling of high

RMS

input frequencies with excellent noise performance.

Maximum DC specs include 1.ꢀLSB ꢁNL, 0.ꢀLSB DNL

(no missing codes).

The digital output can be either differential LVDS or

single-ended CMOS. There are two format options for the

CMOS outputs: a single bus running at the full data rate or

demultiplexed buses running at half data rate. A separate

output power supply allows the CMOS output swing to

range from 0.ꢀV to 3.6V.

Cellular Base Stations

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.
