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
