The LTC2207-14/LTC2206-14 are 105Msps/80Msps,sampling 14-bit A/D converters designed for digiTIzinghigh frequency, wide dynamic range signals up to inputfrequencies of 700MHz. The input range of the ADC canbe opTImized with the PGA front end.The LTC2207-14/LTC2206-14 are perfect for demandingcommunicaTIons applicaTIons, with AC performance thatincludes 77.3dB SNR and 98dB spurious free dynamicrange (SFDR). Ultralow jitter of 80fsRMS allows undersamplingof high input frequencies with excellent noiseperformance. Maximum DC specs include ±1.5LSB INL,±1LSB DNL (no missing codes) over temperature.A separate output power supply allows the CMOS outputswing to range from 0.5V to 3.6V.The ENC+ and ENC– inputs may be driven differentiallyor single-ended with a sine wave, PECL, LVDS, TTL orCMOS inputs. An optional clock duty cycle stabilizer allowshigh performance at full speed with a wide range of clock duty cycles.
