MC145151-2 Parallel-Input (Interfaces with Single-Modulus Prescalers)

MC145151-2 and MC145152-2 Technical Data, Rev. 5

Freescale Semiconductor

5

fV

N Counter Output (Pin 10)

This is the buffered output of the

÷ N counter that is internally connected to the phase detector input. With

this output available, the

÷ N counter can be used independently.

LD

Lock Detector Output (Pin 28)

Essentially a high level when loop is locked (fR, fV of same phase and frequency). Pulses low when loop

is out of lock.

1.2.3

Power Supply

VDD

Positive Power Supply (Pin 3)

The positive power supply potential. This pin may range from + 3 to + 9 V with respect to VSS.

VSS

Negative Power Supply (Pin 2)

The most negative supply potential. This pin is usually ground.
