A/D Converter
AD6645 Data Sheet
FEATURES provides CMOS-compatible digital outputs. It is the fourth
generation in a wideband ADC family, preceded by the AD9042
(12-bit, 41 MSPS), the AD6640 (12-bit, 65 MSPS, IF sampling),
and the AD6644 (14-bit, 40 MSPS/65 MSPS). SNR = 75 dB, fIN 15 MHz, up to 105 MSPS
SNR = 72 dB, fIN 200 MHz, up to 105 MSPS
SFDR = 89 dBc, fIN 70 MHz, up to 105 MSPS
100 dBFS multitone SFDR
IF sampling to 200 MHz
Sampling jitter: 0.1 ps
1.5 W power dissipation
Differential analog inputs
Pin compatible to AD6644
Twos complement digital output format
3.3 V CMOS compatible
Data-ready for output latching Designed for multichannel, multimode receivers, the AD6645 is
part of the Analog Devices, Inc., SoftCell® transceiver chipset.
The AD6645 maintains 100 dB multitone, spurious-free dynamic
range (SFDR) through the second Nyquist band. This breakthrough
performance eases the burden placed on multimode digital
receivers (software radios) that are typically limited by the ADC. …
