Analog Devices, Inc. (ADI), the data converter market share
leader* and a data conversion and signal processing technology
innovator for more than 47 years, today introduced a two-channel,
high-performance 14-bit, 125-MSPS A/D converter that reduces total
power consumption by 22 percent over competing solutions. In
addition to delivering high speed and wide dynamic range at lower
power, the cost-effective and functionally flexible AD9645 A/D
converter is available in a 5-mm × 5-mm package, which represents a
30 percent space savings over the nearest competitor. The new
converter meets the performance and size requirements of the latest
3G and 4G multi-standard cellular infrastructure equipment, such as
CDMA2000, WB-CDMA, LTE, TD-SCDMA and multi-carrier GSM. Other key
applications include battery-powered, hand-held instruments, scopes
and portable medical devices.
The dual AD9645 A/D converter consumes only 122 mW/channel at
125 MSPS (mega samples per second) and features excellent SFDR
(spurious-free dynamic range) performance of 91 dBc at 70 MHz. With
an IF sampling range of up to of 200 MHz, the device is designed
for use in multi-mode digital receiver architectures. A
pin-compatible dual 12-bit version, the AD9635, is also available,
enabling an easy migration path between 12-bit and 14-bit
converters with sampling rates from 20 MSPS to 125 MSPS.

The AD9645 dual A/D converter features a multi-stage,
differential pipelined architecture with integrated
output-error-correction logic. The AD9645 is available in a 32-lead
RoHS-compliant LFCSP and is specified over the industrial
temperature range of –40°C to +85°C. The dual A/D converter
features a space-saving serial 1.8-V LVDS digital output with two
lanes per channel.

- SNR = 74.3 dBFS at fIN up to Nyquist
input frequency; 125 MSPS sampling rate
- ENOB of 12 at fIN up to Nyquist input
frequency
- SFDR = 91 dBc at fIN = 70 MHz
- Excellent DC linearity:
- DNL = ±0.65 LSB typical
- INL = ±1.5 LSB typical
