AD6644

14-Bit, 40 MSPS/65 MSPS Analog-to-Digital Converter AD6644 FEATURES 65 MSPS guaranteed sample rate 40 MSPS version available Sampling jitter < 300 fs 100 dB multitone SFDR 1.3 W power dissipation Differential analog inputs Pin compatible to AD6645 Twos complement digital output format 3.3 V CMOS compatible Data-ready for output latching APPLICATIONS Multichannel, multimode receivers AMPS, IS-136, CDMA, GSM, WCDMA Single channel digital receivers Antenna array processing Communications instrumentation Radar, infrared imaging Instrumentation GENERAL DESCRIPTION The AD6644 is a high speed, high performance, monolithic 14-bit analog-to-digital converter (ADC). All necessary functions, including track-and-hold (TH) and reference, are included onchip to provide a complete conversion solution. The AD6644 provides CMOS-compatible digital outputs. It is the third generation in a wideband ADC family, preceded by the AD9042 (12-bit 41 MSPS) and the AD6640 (12-bit 65 MSPS, IF sampling). Designed...
