High Dynamic Range, 2 Channel IF Amplifier with Power Control 100 - 400 MHz AM55-0024 V7 Clock Diagram 11,12,13,14,15 PCB Schematic 9,10 A2 Data B2 A3 Clock IF Out A IF In A Latch AM55-0024 IF In B IF Out B B3 CLK_B DAT_B B1 LE_B A1 LE_A CLK_A DAT_A 9. All inductors are 470 nH 10. 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. 11. Max Clock Speed = 40 MHz 12. Ton = Toff 13. Tsu = >3ns 14. Thold = >7ns 15. Data clocked in on rising clock edge 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. 8 mm PBGA 3 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
