Anti-jam detector circuit output
Crystal oscillator input
This pin is directly connected to the base of the
Colpitts oscillator input transistor. The value of the
feedback capacitors C13, C14 connected between
XTAL1 and XTAL2 are set by the parallel load
capacitance of the external crystal. Connecting a
200k
resistor from XTAL 1 to ground (in parallel
with C14 ) will maintain oscillation of the crystal in
PD0 mode but increase the receiver current
consumption by approx 20
μ
A.
Crystal oscillator input
Power down input
This tristate input pin is designed to power-up the
device in two modes PD0 to PD2 and PD1 to PD2.
For further information please refer to the Functional
Description.
Anti-jam detector input
DETB input is configured as a high impedance input
where the signal is DC restored on the peak of the
signal, with the aid of capacitor C10.
For further information please refer to the Anti
Jamming Circuit
RSSI output
The RSSI output is configured as a low impedance
output. Tracking of the receive baseband signal is
achieved by an internal current source. See pins 3
and 11.
