DESCRIPTION
16-Bit, 105Msps Serial
Output ADC
The LTC2274 is a 105Msps, 16-bit A/D converter with
a high speed serial interface. It is 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 LTC2274 is perfect for demanding applications 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 under-
sampling 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.
