(5) Data is driven onto D7-D0 by the M-986 until the
RD signal is driven high by the host processor.
Clock Characteristics and Timing
Internal Clock Option:
The internal oscillator is enabled
by connecting a crystal across X1 and X2/CLKIN. The
frequency of CLKOUT is one-fourth the crystal funda-
mental frequency. The crystal should be 20.48 MHz,
fundamental mode, and parallel resonant, with an
effective series resistance of 30 ohms, a power dissi-
pation of 1 mW, and be specified at a load capacitance
of 20 pF.
External Clock Option:
An external frequency source
can be used by injecting the frequency directly in
X2/CLKIN with X1 left unconnected. The external fre-
quency injected must conform to the specifications list-
ed in External Frequency Specifications table on page
6.
Flammability/Reliability Specifications
Reliability:
Flammability:
185 FITS failures/billion hours
Passes UL 94 V-0 tests
