Function
RF input. Modulated RF signal received.
RF output. Modulated RF signal to be transmitted.
Crystal input (see section “Clocking and Power Management” on page 5).
Crystal input (see section “Clocking and Power Management” on page 5).
System clock. Buffered 13-MHz system clock.
Power down. Asserting this input (low), will put the IC in the suspend
mode (X13OUT is 0 when PD is low).
Active LOW reset. Device reset.
PACTL. External power amplifier control. Pull-down or make output.
Data input/output. SERDES bypass mode data transmit/receive.
Data I/O valid. SERDES bypass mode data transmit/receive valid.
IRQ. Interrupt and SERDES bypass mode DIOCLK.
Master-output-slave-input data. SPI data input pin.
Master-input-slave-output data. SPI data output pin.
SPI input clock. SPI clock.
Slave select enable. SPI enable.
VCC = 2.7 V to 3.6 V.
Ground = 0 V.
Tie to ground.
Must be tied to ground.
