Description

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.

Absolu te Maximu m Rati n gs

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 these 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.

This table is not strictly a functional truth table; i.e., it

does not show all possible modes of operation. It is

included as an aid for dc testing.

Notes:

x indicates output state unknown.

U1 and D1 outputs are s equential, i.e., they must be sequenc ed in

the order shown.

U2 and D2 outputs are c omb inat ional, i.e., they need only input s to

obtain the desired output state.
