74HCT297 filter equivalent, digital phase-locked-loop filter.
* Digital design avoids analog compensation errors
* Easily cascadable for higher order loops
* Useful frequency range:
– DC to 55 MHz typical.
These devices contain all the necessary circuits, with the exception of the divide-by-n counter, to build first order p.
The 74HC/HCT297 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT297 are designed to provide a simple, cost-effective solution to .
