Interfaces with Dual–Modulus Prescalers
The MC145149 contains two PLL Frequency Synthesizers which share a
common serial data port and common reference oscillator. The device
contains two 14–stage R counters, two 10–stage N counters, and two
7–stage A counters. All six counters are fully programmable through a serial
port. The divide ratios are latched into the appropriate counter latch
according to the last data bits (control bits) entered.
When combined with external low–pass filters and voltage controlled
oscillators (VCOs), the MC145149 can provide all the remaining functions
for two PLL frequency synthesizers operating up to the device’s frequency
limit. For higher VCO frequency operation, a down mixer or dual–modulus
prescaler can be used between the VCO and the synthesizer IC.
