ML145155
Serial–Input PLL
Frequency Synthesizer
Interfaces with Single–Modulus Prescalers
Legacy Device:
Motorola/Freescale MC145155-2
The ML145155 is programmed by a clocked, serial input,
16–bit data stream. The device features consist of a reference
oscillator, selectable–reference divider, digital–phase detector,
14–bit programmable divide–by–N counter, and the necessary
shift register and latch circuitry for accepting serial input
data.
