All capacitors are 10,000 pF 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. 8 mm PBGA CLK_A B1 A1 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 (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. 3 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
