Clock Generator
The Z80182/Z8L182 ZIP
clock generator to supply system clock. The required
clock is easily generated by connection a crystal to the
external terminals (XTAL,EXTAL). The clock output runs at
half the crystal frequency for X2 mode.
Recommended characteristics of the crystal and the values
for the capacitor are as follows (the values will change with
crystal frequency).
