Loop Filter Constants
This table shows the constants K1 and K2 that are used with the equations on page 6 to calculate the external loop filter
components.Loop Filter Contstants for MK1574-01A
PC Board Layout
A proper board layout is critical to the successful use of the MK1574-01A/B. In particular, the CAP1 and CAP2 pins
are very sensitive to noise and leakage (CAP1 at pin 4 is the most sensitive). Traces must be as short as possible
and the capacitor and resistor must be mounted next to the device as shown to the right. The capacitor connected
between pins 3 and 5 is the power supply decoupling capacitor. The high frequency output clocks on may benefit
from a series 33
resistor connected close to the pin (not shown).
Clock Multipliers/Accuracies
In the table on page 2 are the actual multipliers stored in the MK1574-01A/B ROM, which yield the exact values
shown for the output clocks.
