1994 Aug 31
853-0908 13720
DESCRIPTION
The NE/SE564 is a versatile, high guaranteed frequency
phase-locked loop designed for operation up to 50MHz. As shown
in the Block Diagram, the NE/SE564 consists of a VCO, limiter,
phase comparator, and post detection processor.
FEATURES
Operation with single 5V supply
TTL-compatible inputs and outputs
Guaranteed operation to 50MHz
External loop gain control
Reduced carrier feedthrough
No elaborate filtering needed in FSK applications
Can be used as a modulator
Variable loop gain (externally controlled)
APPLICATIONS
High speed modems
FSK receivers and transmitters
Frequency Synthesizers
