Description
The M/A-COM AM55-0024 is a dual channel IF
amplifier and digital attenuator packaged in a multi-
layer multi-chip module (MCM). Gain control is via
two separate serial logic interfaces. The part utilizes
Plastic Ball Grid Array (PBGA) interconnect
technology to achieve high circuit density and
superior performance. This device is ideal for GSM/
DCS/PCS digital base station applications where
high dynamic range gain control is required.

Serial Interface

10.All capacitors are 10,000 pF
Each channel in the AM55-0024 is independently
controllable with a 3 wire serial interface: Clock,
Data, and Latch Enable. These lines can be
shared based on application requirements. The
attenuator within the device is controlled with a 6 bit
word, enabling the selection of 64 possible states.
The highest gain state is '000000', and the lowest is
'111111'. The sequence for shifting the data is as
follows: Present data (Least significant bit first),
strobe clock, repeat until 6 bits have been
presented and clocked, then strobe the latch
enable line, which implements the state change.
Operating Instructions
The AM55-0024 can operate with voltages
between +3 V and +5 V. The amplifier voltages are
applied to pins A2, A3, B2 and B3 respectively.
A1 and B1 supply the Vdd to the logic circuits and
thus must be the same levels as the logic driving
the Clock, Latch Enable and Data ports. The
amplifiers and logic circuits are independent and
need not be the same levels.
