www.DataSheet4U.com ML145159 Serial-Input PLL Frequency Synthesizer with Analog Phase Detector 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 programmed serially through a common data input and latched into the appropriate counter latch, according to the last data bit (control bit)
