ML145157
Serial–Input PLL
Frequency Synthesizer
Interfaces with Single–Modulus Prescalers
Legacy Device: Motorola/Freescale MC145157-2
The ML145157 has a fully programmable 14–bit reference
counter, as well as a fully programmable ÷ N counter. The
counters are programmed serially through a common data
input and latched into the appropriate counter latch, accord-
ing to the last data bit (control bit) entered.
