LTC2216/LTC2215

16-Bit, 80Msps/65Msps

Low Noise ADC

DESCRIPTION

The LTC

®

2216/LTC2215 are 80Msps/65Msps sampling 16-

bit A/D converters designed for digitizing high frequency,

wide dynamic range signals with input frequencies up to

400MHz. The input range of the ADC is ﬁxed at 2.75V

P-P

.

The LTC2216/LTC2215 are perfect for demanding com-

munications applications, with AC performance that

includes 81.5dBFS noise ﬂoor and 100dB spurious free

dynamic range (SFDR). Ultra low jitter of 85fs

RMS

allows

undersampling of high input frequencies while maintaining

excellent noise performance. Maximum DC specs include

±3.5LSB INL, ±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.

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.
