描述 Description

DESCRIPTION
The LTC®2240-10 is a 170Msps, sampling 10-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2240-10 is perfect for demanding communications applications with AC performance that includes 60.6dB SNR and 80dB SFDR. Ultralow jitter of 95fsRMS allows IF undersampling with excellent noise performance.
DC specs include ±0.3LSB INL (typ), ±0.1LSB DNL (typ) and no missing codes over temperature.
The digital outputs can be either differential LVDS, or single-ended CMOS. There are three format options for the CMOS outputs: a single bus running at the full data rate or two demultiplexed buses running at half data rate with either interleaved or simultaneous update. A separate output power supply allows the CMOS output swing to range from 0.5V to 2.625V.
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 over a wide range of clock duty cycles.FEATURES
