selected if RSSI is required in TDMA mode. The
RSSI is always powered on in FM mode
RSSI off.
RSSI circuitry off when TDMA receive
mode selected. This is the default state in TDMA
mode
TX PLL ON.
Transmit PLL circuits remain powered
on in powerdown mode.
TX PLL OFF.
Transmit PLL circuits are powered off
in powerdown mode.
RX PLL ON.
Receive PLL and VCO circuits remain
powered on in powerdown mode.
RX PLL OFF.
Receive PLL and VCO circuits are
powered off in powerdown mode.
These power control modes are activated by the
PCA pin. The PCA pin must normally be held low
whilst a power control instruction is loaded via the
serial bus. The power mode is not activated however
until the PCA line is taken high. This allows accurate
timing of the power modes. The exception is the Alt
RX/TX mode which is loaded while PCA is low. The
receive and transmit modes can then be toggled with
the PCA pin.
In addition the receive LO Oscillator can be powered
down by setting VPD (Word 7 - Bit 4) to one. This
allows the LO to be provided differentially from an
external oscillator.
