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 61/2 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. 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.
