Analog Devices AD6600

The AD6600 may be used as a stand-alone sampling chip, or it may be combined with the AD6620 Digital Receive Signal Processor. The AD6620 provides 10 dB–25 dB of additional processing gain before passing data to a fixed- or floating-point DSP. The AD6630 is easily matched to inexpensive SAW filters from 70 MHz to 250 MHz.

APPLICATIONS

Communications Receivers PCS/Cellular Base Stations GSM, CDMA, TDMA Wireless Local Loop, Fixed Access Dual Channel, Gain-Ranging ADC with RSSI AD6600 two input channels, each with 1 GHz input amplifiers and 30 dB of automatic gain-ranging circuitry. Both channels are sampled with a 450 MHz track-and-hold followed by an 11-bit, 20 MSPS analog-to-digital converter. Digital RSSI outputs, an A/B channel indicator, a 2× Clock output, references, and control circuitry are all on-chip. Digital output signals are two’s complement, CMOS-compatible and interface directly to 3.3 V or 5 V digital processing chips.
