The LUCDA4044 consists of two digital phase detec-
tors, a charge pump, and an amplifier. In combination
with a voltage-controlled multivibrator, this device is
useful in a broad range of phase-locked loop (PLL)
applications. The circuit accepts TTL waveforms at
the R and V inputs and generates an error voltage
that is proportional to frequency and/or phase differ-
ence.
Phase detector #1 is intended for use in systems
requiring zero frequency and phase at lock. Phase
detector #2 is used if quadrature lock is desired.
Phase detector #2 can also be used to indicate that
the main loop (utilizing phase detector #1) is out of
lock. This LUCDA4044 is a direct replacement for the
Motorola* MC4044.
