HEF4750V - Frequency synthesizer

Description

The HEF4750V frequency synthesizer is one of a pair of LOCMOS devices, primarily intended for use in high-performance frequency synthesizers, e.g.

in all communication, instrumentation, television and broadcast applications.

Features

  • offered (in combination with HEF4751V) are:.
  • Wide choice of reference frequency using a single crystal.
  • High-performance phase comparator  low phase noise  low spurii.
  • System operation to > 1 GHz.
  • Typical 15 MHz input at 10 V.
  • Flexible programming: frequency offsets ROM compatible fractional channel capability.
  • Programme range 61⁄2 decades, including up to 3 decades of prescaler control.
  • Division range extension by cascading.
