The VCO output is then routed through a programmable divider by 8 or 16 to create the TX and RX LO signals.
The TRF2443 features a lock-detect output pin (LOCKDET, pin 5). This is a digital output that is high when both
RX and TX synthesizers are locked, and it is low if one or both synthesizers are unlocked (or lose lock).
The TRF2443 provides cross-polarization interference cancellation (XPIC) support via an integrated XPIC output
amplifier and receiver chain. The XPIC output amplifier transmits the signal taken at the receiver demodulator
input. The XPIC receiver section downconverts the input signal to baseband I and Q. It includes an IF VGA
followed by a demodulator and a baseband amplifier.
