Analog's 14-Bit ADC Fortifies 3G/WiMAX Basestations

Delivering sampling rates to 150 Msamples/s, the AD9640 dual, 14-bit a/d converter meets the rate requirements for all wireless standards including WiMAX. Previously, sampling rates beyond 135 MSPS could only be realized by single-channel converters, reportedly. The AD9640 consumes 390 mW of power per channel and specifies a SNR of 72.7 dBFS, SFDR of 85 dBc, and, with a 70 MHz IF, it is also capable of supporting IFs as high as 450 MHz. Additionally, the device is said to be the industry’s first to integrate digital features including a block that monitors the incoming composite signal power, and indicates whether the gain of the receiver needs to be increased or decreased. Sampling now with production quantities expected in April 2007, the device is available in 12- and 14-bit resolutions with sample rates of 80, 105, 125 and 150 Msamples/s. Both CMOS and LVDS output modes are supported. Prices range from $37.50 and $87.50 each/1,000. ANALOG DEVICES INC., Norwood, MA. (800) 262-5643.
