The LTC2222-11 is a 105Msps, sampling 11-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2222-11 is perfect for demanding communications applications with AC performance that includes 65.4dB SNR and 80dB spurious free dynamic range for signals up to 150MHz. Ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance.
DC specs include ±0.15LSB INL (typ), ±0.1LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.25LSBRMS.
A separate output power supply allows the CMOS output swing to range from 0.5V to 3.3V.
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 at full speed for a wide range of clock duty cycles.
