Datasheet Specifications

Part number: 74HC297
Manufacturer: Philips
File Size: 101.43 KB
Datasheet: 74HC297_PhilipsSemiconductors.pdf
Description: Digital phase-locked-loop filter

Features

* Digital design avoids analog compensation errors
* Easily cascadable for higher order loops
* Useful frequency range:
* DC to 55 MHz typical (K-clock)
* DC to 35 MHz typical (I/D-clock)
* Dynamically variable bandwidth
* Very narrow bandwidth

Applications

* These devices contain all the necessary circuits, with the exception of the divide-by-n counter, to build first order phase-locked-loops. Both EXCLUSIVE-OR (XORPD) and edge-controlled (ECPD) phase detectors are provided for maximum flexibility. The input signals for the EXCLUSIVE-OR phase detector
