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...
