PRODUCT DESCRIPTION
The AD6600 mixed-signal receiver chip directly samples signals
at analog input frequencies up to 250 MHz. The device includes
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 10MSPS
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.
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.
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.
Units are available in plastic, surface-mount packages (44-lead
LQFP) and specified over the industrial temperature range
(–40
°
C to +85
°
C).
