LTC2258IUJ-12#PBF

LTC2258IUJ-12#PBF is a sampling 12bit A/D converter designed for digitizing high frequency, wide dynamic range signals. It is perfect for demanding communications applications with AC performance that includes 71.1dBSNR and 88dB spurious free dynamic range (SFDR). Ultralow jitter of 0.17psRMS allows undersampling of IF frequencies with excellent noise performance. 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. Applications include communications, cellular base stations, software-defined radios, portable medical imaging, multi-channel data acquisition, and non-destructive testing.
