DESCRIPTION:
The IDT5V991A is a high fanout 3.3V PLL based clock driver intended
for high performance computing and data-communications applications. A
key feature of the programmable skew is the ability of outputs to lead or lag
the REF input signal. The IDT5V991A has eight programmable skew
outputs in four banks of 2. 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 synchronously
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.
