Interfaces with Dual–Modulus Prescalers

The MC145159–1 has a programmable 14–bit reference counter, as well as

fully programmable divide–by–N/divide–by–A counters. The counters are

programmed serially through a common data input and latched into the

appropriate counter latch, according to the last data bit (control bit) entered.

When combined with a loop filter and VCO, this device can provide all the

remaining functions for a PLL frequency synthesizer operating up to the

device’s frequency limit. For higher VCO frequency operations, a down mixer or

a dual–modulus prescaler can be used between the VCO and the PLL.

• Operating Temperature Range: – 40 to 85°C

• Low Power Consumption Through Use of CMOS Technology

• 3.0 to 9.0 V Supply Range

• On– or Off–Chip Reference Oscillator Operation

• Compatible with the Serial Peripheral Interface (SPI) on CMOS MCUs

• ÷ R Range = 3 to 16383

• ÷ N Range = 16 to 1023, ÷ A Range = 0 to 127

• High–Gain Analog Phase Detector

• See Application Note AN969
