37.5 MHz (-15), see Table 1 for conditions
On-chip loop filter
Single 5 volt power supply
Low power CMOS technology
Small 8-pin SOIC package
The MK9173-01 and MK9173-15 provide the analog PLL
circuit blocks to implement a frequency multiplier. Because
the device is configured to use an external divider in the PLL
clock feedback path, a large divider can be used to result in a
large frequency multiplication ratio. This is useful when using
a low frequency input clock to generate a high frequency
output clock. The MK9173-01/15 contains a phase detector,
charge pump, loop filter, and voltage-controlled oscillator
(VCO). The ICS674-01 can be used as the external feedback
divider.
A common application of the MK9173-01/-15 is the
implementation of a video genlock circuit. Because of this,
the MK9173-01/-15 inputs operate on the negative-going
clock edge.
The MK9173-01/15 is pin and function compatible to the
AV9173-01/15. Please refer to page 4 regarding performance
differences. For new video genlock designs, please refer to the
ICS673-01, ICS1522 or ICS1523.
