Wireless Components
Specification, August 2003
8
FI
VCO-Frequency
Input with highly sensitive preamplifier for
14-bit N-counter and 7-bit A-counter. With
small input signals AC coupling must be
set up, where DC coupling can be used
for large input signals.
9
V
SS1
Ground for the preamplifiers, counters,
phase detector and charge pump.
(Note: The pins

SS and VSS
1 have to have the
same supply voltage.)
10
PD
Phase Detector
Tristate charge pump output. The inte-
grated, positive and negative current
sources can be programmed with respect
to their current density by means of the
serial control. Activation and deactivation
depend on the phase relationship of the
scaled-down input signals FI:N, RI:R.
(See phase detector output waveforms.)

In standby mode the PD-output is set to
tristate. The assignment of the current
sources to the output signals of the phase
detector can be swapped in it’s polarity,
i.e. the sign of the phase detector con-
stant can be controlled.
Only this pin has limited build-in ESD pro-
tection of 400V.

Positive supply voltage for the preamplifi-
ers, counters, phase detector and charge
pump.
