14-Bit, 105Msps/80Msps
ADCs
DESCRIPTIO
The LTC®2207-14/LTC2206-14 are 105Msps/80Msps,
sampling 14-bit A/D converters designed for digitizing
high frequency, wide dynamic range signals up to input
frequencies of 700MHz. The input range of the ADC can
be optimized with the PGA front end.
The LTC2207-14/LTC2206-14 are perfect for demanding
communications applications, with AC performance that
includes 77.3dB SNR and 98dB spurious free dynamic
range (SFDR). Ultralow jitter of 80fsRMS allows under-
sampling of high input frequencies with excellent noise
performance. Maximum DC specs include ±1.5LSB INL,
±1LSB DNL (no missing codes) over temperature.
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.
