Phase Locked Frequency Controller

FEATURES

DESCRIPTION

•

Precision Phase Locked Frequency

The UC1635 family of integrated circuits was designed for use in preci-

sion speed control of DC motors. An extension to the UC1633 line of

phase locked controllers, these devices provide access to both of the

digital phase detector’s inputs, and include a reference frequency di-

vider output pin. With this added flexibility, this family of controllers can

be used to obtain phase synchronization of multiple motors.

Control System

•

Crystal Oscillator

Programmable Reference Frequency

Dividers

•

Phase Detector with Absolute Frequency

Steering

A reference frequency can be generated using the device’s crystal oscil-

lator and programmable dividers. The oscillator operates using a broad

range of crystals, or, can function as a buffer stage to an external fre-

quency source.

Separate Divider Outputs and Phase

Detector Input Pins

Double Edge Option on the Frequency

Feedback Sensing Amplifier

The phase detector responds proportionally to the phase error between

the detector’s minus input pin and the sense amplifier output. This

phase detector includes absolute frequency steering to provide maxi-

mum drive signals when any frequency error exists. This feature allows

optimum start-up and lock times to be realized.

•

Two High Current Op Amps

5V Reference Output

Two op-amps are included that can be configured to provide necessary

loop filtering. The outputs of these op-amps will source or sink in excess

of 16mA, so they can provide a low impedance control signal to driving

circuits.

Additional features include a double edge option on the sense amplifier

that can be used to double the loop reference frequency for increased

loop bandwidths. A 5V reference output can be used to accurately set

DC operating levels.
