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. 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 612 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.
SUPPLY VOLTAGE
RATING
0,5 to +15
RECOMMENDED OPERATING
9,5 to 10,5 V
APPLICATION INFORMATION
Some examples of applications for the HEF4750V in
combination with the HEF4751V are:
VHF/UHF mobile radios.
HF s.s.b. transceivers.
Airborne and marine communications and navaids.
Broadcast transmitters.
High quality radio and television receivers.
High performance citizens band equipment.
Signal generators.
