DESCRIPTION
12-Bit, 170Msps ADC
The LTC2240-12 is a 170Msps, sampling 12-bit A/D con-
verter designed for digitizing high frequency, wide dynamic
range signals. The LTC2240-12 is perfect for demanding
communications applications with AC performance that
includes 65.6dB SNR and 80dB SFDR. Ultralow jitter of
95fsRMS allows IF undersampling with excellent noise
performance.
DC specs include ±0.6LSB INL (typ), ±0.4LSB DNL (typ)
and no missing codes over temperature.
The digital outputs can be either differential LVDS, or
single-ended CMOS. There are three format options for
the CMOS outputs: a single bus running at the full data
rate or two demultiplexed buses running at half data rate
with either interleaved or simultaneous update. A separate
output power supply allows the CMOS output swing to
range from 0.5V to 2.625V.
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 allows high
performance over a wide range of clock duty cycles.
