Linear Technology LTC2260IUJ-12#PBF

Description
The LTC2261-12/LTC2260-12/LTC2259-12 are 12-bit, 125/105/80Msps ultralow power 1.8V ADCs designed for digitizing high-frequency, wide dynamic range signals. They are ideal for demanding communications applications with AC performance that includes 70.8dB SNR and 85dB spurious free dynamic range (SFDR). Ultralow jitter of 0.17pSRMS allows undersampling of IF frequencies with excellent noise performance.
DC specs include 0.3LSB INL (typical), ±0.1LSB DNL (typical) and no missing codes over temperature. The transition noise is a low 0.3LSBRMS.
The digital outputs can be either full-rate CMOS, double-data rate CMOS, or double-data rate LVDS. A separate output power supply allows the CMOS output swing to range from 1.2V to 1.8V.
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.
