Description

The LTC®2234 is a 135Msps, sampling 10-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2234 is perfect for demanding communications applications with AC performance that includes 60.5dB SNR and 75dB spurious free dynamic range for signals up to 400MHz. Ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance.

DC specs include ±0.2LSB INL (typ), ±0.1LSB DNL (typ)and ±0.8LSB INL, ±0.6LSB DNL over temperature. The  transition noise is a low 0.12LSBRMS.

A separate output power supply of LTC2234 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.
