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 of LUCDA4044 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 he main loop (utilizing phase detector #1) is out of lock. This LUCDA4044 is a direct replacement for the Motorola* MC4044.
