HEF4750V Features
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. A combination of analogue and digital techniques results in an integrated circuit that enables high performance. The complementary device is the universal divider type HEF4751V.
Together with a standard prescaler, the two LOCMOS integrated circuits offer low-cost single loop synthesizers with full professional performance. Salient 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 6 1/2 decades, including up to 3 decades of prescaler control.
* Division range extension by cascading.
* Built-in phase modulator.
* Fast lock feature.
* Out-of-lock indication.
* Low power dissipation and high noise immunity.
