When LE is high, latch is clear and content of SPI control the attenuator. When LE is low, data in SPI is latched. 2 DATA Serial data input. The data and clock pins allow the data to be entered serially into SPI and is independent of Latch state. 3 CLK Serial clock input. 4, 22 N/C No connect or open. This pin is not connected in this module 6 RFIN Input, matched to 50 ohms. Internally DC blocked. 8 VCC_AMP1 Supply Voltage to AMP1. This pin is connected internally to 2 bypass capacitors (100 pF, 0.1 uF) followed by a 68 nH inductor inside the module. 14 VCC_AMP2 Supply Voltage to AMP2. This pin is connected internally to 2 bypass capacitors (100 pF, 0.1 uF) followed by a 47 nH inductor inside the module. 16 RFOUT Output matched to 50 ohms. Internally DC blocked. 28 VCC_SPI SPI and DSA DC supply. Internal connection to 0.1 uF bypass capacitor. 5, 7, 9-13, 15,17-21, 23-27 GND RF/DC Ground Connection Backside Pad GND RF/DC Ground Connection Evaluation Board PCB Information TriQuint PCB 1080956 Material and Stack-up |
