LTC2208

16-Bit, 130Msps ADC

FEATURES

DESCRIPTIO

■

Sample Rate: 130Msps

The LTC^®2208 is a 130Msps, sampling 16-bit A/D con-

verterdesignedfordigitizinghighfrequency,widedynamic

range signals with input frequencies up to 700MHz. The

input range of the ADC can be optimized with the PGA

front end.

P-P

The LTC2208 is perfect for demanding communications

applications, with AC performance that includes 78dBFS

Noise Floor and 100dB spurious free dynamic range

(SFDR). Ultra low jitter of 70fs

allows undersampling

RMS

ofhighinputfrequencieswithexcellentnoiseperformance.

Maximum DC specs include ±±LSB ꢀNL, ±1LSB 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 0.5V 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.
