INTERFACES WITH DUAL–MODULUS PRESCALERS
Legacy Device: Motorola MC145159-1
The ML145159 has a programmable 14–bit reference
counter, as well as fully programmable
divide–by–N/divide–by–A counters. The counters are pro-
grammed 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 syn-
thesizer operating up to the device's frequency limit. For high-
er VCO frequency operations, a down mixer or a dual–modu-
lus prescaler can be used between the VCO and the PLL.
• Operating Temperature Range: TA – 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, P A Range = 0 to 127
• High–Gain Analog Phase Detector
• See Application Note AN969
Note: Lansdale lead free (Pb) product, as it
becomes available, will be identified by a part
number prefix change from ML to MLE.
