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 functionality is required.

Serial Interface
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 (MSB first),
strobe clock, repeat until 6 bits have been presented and
clocked, then strobe the latch enable line, which
implements the state change.
