Dual Channel, Gain-Ranging  
ADC with RSSI  
a
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 con-  
trol 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.

The primary use for the dual analog input structure is sampling  
both antennas in a two-antenna diversity receiver. However,  
Channels A and B may also be used to sample two independent  
IF signals. Diversity, or dual-channel mode, is limited to 10 MSPS  
per channel. In single-channel mode, the full clock rate of  
20 MSPS may be applied to a single carrier.  
The AD6600 may be used as a stand-alone sampling chip, or it  
may be combined with the AD6620 Digital Receive Signal Pro-  
cessor. The AD6620 provides 10 dB–25 dB of additional pro-  
cessing gain before passing data to a fixed- or floating-point DSP.  
APPLICATIONS  
Driving the AD6600 is simplified by using the AD6630 differen-  
tial IF amplifier. The AD6630 is easily matched to inexpensive  
SAW filters from 70 MHz to 250 MHz.  
Communications Receivers  
PCS/Cellular Base Stations  
GSM, CDMA, TDMA  
Designed specifically for cellular/PCS receivers, the AD6600  
supports GSM, IS-136, CDMA and Wireless LANs, as well as  
proprietary air interfaces used in WLL/fixed-access systems.  
Wireless Local Loop, Fixed Access  
PRODUCT DESCRIPTION  
The AD6600 mixed-signal receiver chip directly samples signals  
at analog input frequencies up to 250 MHz. The device includes  
Units are available in plastic, surface-mount packages (44-lead  
LQFP) and specified over the industrial temperature range  
(–40°C to +85°C).
