DP8224 Clock Generator and Driver
General Description
The DP8224 is a clock generator driver contained in a stan-
dard 16-pin dual-in-line package The chip which is fabri-
cated using Schottky Bipolar technology generates clocks
and timing for the 8080A microcomputer family
Included in the DP8224 is an oscillator circuit that is con-
trolled by an external crystal which is selected by the de-
signer to meet a variety of system speed requirements Also
included in the chip are circuits that provide a status strobe
for the DP8228 or DP8238 system controllers power-on re-
set for the 8080A microprocessor and synchronization of
the READY input to the 8080A
