Description

The LUCDA4044 consists of two digital phase detec­tors, 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 differ­ence.

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 f or the

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings
can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the
device is not implied at thes e or any other conditions in
excess of those given in the operational sections of the
data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.

Notes:
x indicates output state unknown.

U1 and D1 outputs are sequential, i.e., they must be sequenced in
the order shown.

U2 and D2 outputs are combinational, i.e., they need only inputs to
obtain the desired output state.
