Clock
* Preliminary value including pin parasitics
The device’s on-chip oscillator has a high-gain, parallel-resonant amplifier, for connection
to a crystal or ceramic resonator, or any suitable external clock source (XTAL1 = Input,
XTAL2 = Output). The crystal must be AT cut, 1 MHz to 8 MHz maximum, with a series
resistance (RS) less than or equal to 100
suitable external clock source.
The crystal must be connected across XTAL1 and XTAL2 using the recommended capac-
itors from each pin to ground. The typical capacitor value is 10 pF for 8 MHz. Check with
the crystal supplier for the optimum capacitance.
Zilog’s ZGP323H supports crystal, resonator, and oscillator. Most resonators have a fre-
quency tolerance of less than +/-0.5% which is adequate for remote control applications.
The typical resonator has a very fast start up time on the order of a few hundred microsec-
onds.
Most crystals have a frequency tolerance of less than 50 ppm (+/-0.005%). Crystal oscilla-
tors, however, require a much longer start-up time because the large loading capacitance
slows down oscillation start-up. Zilog
than 10 pF for crystal oscillators. If the stray capacitance of the PCB or the crystal is high,
the loading capacitance C1 and C2 should be further reduced to ensure stable oscillation
