6
V
DD
Positive supply voltage for serial control logic.
2
V
SS
Ground for serial control logic.
13
V
DD1
Positive supply voltage for the preamplifiers, counters, phase
detector and charge pump.
11
V
SS1
Ground for the preamplifiers, counters, phase detector and charge
pump.
Note: The pins
V
DD and VDD
1 respectively VSS and VSS1 have to
have the same supply voltage.
3EN
3-Line Bus: Enable
Enable line of the serial control with internal pull-up resistor. When
EN = H the input signals CLK and DA are disabled internally. When
EN = L the serial control is activated. The received data are
transferred into the latches with the positive edge of the EN-signal.
4DA
3-Line Bus: Data
Serial data input with internal pull-up resistor. The last two bits
before the EN-signal define the destination address. In a byte-
oriented data structure the transmitted data have to end with the
EN-signal, i.e. bits to be filled in (don’t care) are transmitted first.
5
CLK
3-Line Bus: Clock
Clock line with internal pull-up resistor. The serial data are read into
the internal shift register with the positive edge (see pulse diagram
for serial data control).
7
MOD
Modulus Control Output for external dual modulus prescaler. The
modulus output is low at the beginning of the cycle. When the
a-counter has reached its set value, MOD switches to high. When
the n-counter has reached its set value, MOD switches to low
again, and the cycle starts from the top. When the prescaler has the
counter factor P or P + 1 (P for MOD = H, P +1 for MOD = L), the
overall scaling factor is NP + A. The value of the a-counter must be
smaller than that of the n-counter. The trigger edge of the modulus
signal to the input signal can be selected (see programming tables
and MOD A, B) according to the needs of the prescaler. In single
modulus operation and for standby operation in dual modulus
operation, the output is low.
