DESCRIPTION

The ADS58C20 and ADS58C23 are dual IF receivers for wideband, multi-mode cellular infrastructure base

stations. Each channel provides high dynamic performance up to 125 MHz of bandwidth, with optimized bands of

40- and 75-MHz. The IF receiver architecture eases front end filter design for wide bandwidth receivers. The

receivers have integrated buffers at the analog inputs with benefits of uniform performance and input impedance

across a wide frequency range.

The ADS58C20 is a high performance part with superior specifications for single/multi-mode cellular base-station

receivers that include multi-carrier GSM. It can also process other cellular protocols such as TDS-CDMA/3G/LTE

and prior generation systems.

The ADS58C23 offers the same functionality and pinout as ADS58C20 but with reduced minimum performance

specifications for lower cost and performance systems, such as TDS-CDMA/3G/LTE single/multi-mode receivers

(when GSM is not required). It can also process prior generation protocols.

The devices are available in a 80-pin TQFP package, and are specified over the full industrial temperature range

(–40°C to 85°C).
