HIGH FREQUENCY PLL CLOCK GENERATOR
Features
* ill latch the information present on the M[6:0] and N[1:0] inputs into the M and N counters. When the P_LOAD signal is LOW the input latches will be transparent and any changes on the M[6:0] and N[1:0] inputs will affect the FOUT output pair. To use the serial port the S_CLOCK signal samples the inf
MC12439, HIGH FREQUENCY PLL CLOCK GENERATOR
The internal oscillator uses the external quartz crystal as the basis of its frequency reference.
The output of the reference oscillator is sent directly to the phase detector.
With a 16.66MHz crystal, this provides a reference frequency of 16.66MHz.
Although this data sheet illustrates functionalit
MOTOROLA SEMICONDUCTOR TECHNICAL DATA High Frequency Clock Generator The MC12439 is a general purpose synthesized clock source targeting applications that require both serial and parallel interfaces.
Its internal VCO will operate over a range of frequencies from 400 to 800MHz.
The differential PECL output can be configured to be the VCO frequency divided by 1, 2, 4, or 8.
With the output configured to divide the VCO frequency by 1, and with a 16.66MHz external quartz crystal used to provide th
