DESCRIPTION
16-Bit, 80Msps/65Msps
Serial Output ADC
The LTC2273/LTC2272 are 80Msps/65Msps, 16-bit A/D
converters with a high speed serial interface. They are
designed for digitizing high frequency, wide dynamic
range signals with an input bandwidth of 700MHz. The
input range of the ADC can be optimized using the PGA
front end. The output data is serialized according to the
JEDEC serial interface for data converters specication
(JESD204).
The LTC2273/LTC2272 are perfect for demanding applica-
tions where it is desirable to isolate the sensitive analog
circuits from the noisy digital logic. The AC performance
includes a 77.7dB Noise Floor and 100dB spurious free
dynamic range (SFDR). Ultra low internal jitter of 80fs
RMS allows undersampling of high input frequencies
with excellent noise performance. Maximum DC specs
include ±4.5LSB INL and ±1LSB DNL (no missing codes)
over temperature.
The encode clock inputs, ENC+ and ENC–, may be driven
differentially or single-ended with a sine wave, PECL,
LVDS, TTL or CMOS inputs. A clock duty cycle stabilizer
allows high performance at full speed with a wide range
of clock duty cycles.
