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 2.75VP-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 85fsRMS 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.
