AD6600ASTZ-REEL 数据手册

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 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.

FEATURES

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).
