Description
The PI6C3Q99X family is a high fanout 3.3V PLL-based clock driver
intended for high performance computing and data-communica-
tions applications. 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 the outputs are synchro-
nously enabled. However, if GND/sOE is held high, all the outputs
except 3Q0 and 3Q1 are synchronously disabled. Furthermore, when
the V
CCQ
/PE is held high, all the outputs are synchronized with the
positive edge of the REF clock input. When V
CCQ
/PE is held low,
all the outputs are synchronized with the negative edge of REF. Both
devices have LVTTL outputs with 12mA balanced drive outputs.
