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.

Features

■ Typical propagation delay 9.0 ns (through phase detector)

■ Includes charge pump and amplifier

■ Available in 14-pin DIP or SONB

Applications

■ Frequency synthesizers

■ Clock recovery
