ML145158
Serial–Input PLL
Frequency Synthesizer
Interfaces with Dual–Modulus Prescalers
Legacy Device: Motorola/Freescale MC145158-2
The ML145158 has a fully programmable 14–bit reference
counter, as well as fully programmable ÷ N and ÷ 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.
