Description
ThePI6C3Q99xfamilyisa3.3VPLL-basedclockdriver intendedfor
high-performance computing and data-communication applica-
tions. A key feature of the programmable skew is the ability of
outputs to lead or lag the REF input signal. The PI6C3Q991 has 8
programmable skew outputs in 4 banks of 2, while the PI6C3Q993
has 6 programmable skew outputs and 2 zero skew outputs. Skew
is controlled by 3-level input signals that may be hard-wired to
appropriate HIGH-MID-LOW levels.
When the GND/sOE pin is held LOW, all outputs are synchronously
enabled.However,ifGND/sOEisheldHIGH,alloutputsexcept3Q0
and 3Q1 are synchronously disabled. Furthermore, when the V CCQ
/PE is held HIGH, all outputs are synchronized with the positive
edge of the REF clock input. When VCCQ /PE is held LOW, all
outputs are synchronized with the negative edge of REF. Both
devices have LVTTL 12mA balanced drive outputs.
