THE LFCSP HAS AN EXPOSED PAD THAT MUST BE CONNECTED TO GND. Figure 4. Pin Configuration Table 4. Pin Function Descriptions Pin No. Mnemonic Description 1, 3, 5, 7, 18, 20, 22, 24, 28, 30 GND Ground Pins. 2 RX1_RF Channel 1 RF Input. 4, 21, 27 AVDD Analog Power Supply. The supply range is 3.3 V ± 5%. Place decoupling capacitors (0.1 µF, 1 nF, and 10 pF) to the ground plane as close as possible to this pin. 6 RX2_RF Channel 2 RF Input. 8 RX2_O Channel 2 Baseband Output. 9 RX2_OB Channel 2 Complementary Baseband Output. 10 LE Load Enable, CMOS Input. When LE goes high, data stored in the shift registers is loaded into one of the four latches; the control bits select the latch. 11 CLK Serial Clock Input. This serial clock clocks in the serial data to the registers. Data latches into the 32-bit shift register on the CLK rising edge. This input is a high impedance CMOS input. 12 DATA Serial Data Input. The serial data loads MSB first and the two LSBs are the control bits. This input is a high impedance CMOS input. 13 CE Chip Enable. A logic low on this pin powers down the device. 14 DOUT Serial Data Output. 15 ATEST Analog Test Output 16 RX4_OB Channel 4 Complementary Baseband Output. 17 RX4_O Channel 4 Baseband Output. 19 RX4_RF Channel 4 RF Input. 23 RX3_RF Channel 3 RF Input. 25 RX3_O Channel 3 Baseband Output. 26 RX3_OB Channel 3 Complementary Baseband Output. 29 LO_IN Local Oscillator Input. 31 RX1_OB Channel 1 Complementary Baseband Output. 32 RX1_O Channel 1 Baseband Output. EPAD Exposed Pad. The LFCSP has an exposed pad that must be connected to GND. Rev. 0 | Page 6 of 15 |
