3.3V PROGRAMMABLE
SKEW DUAL PLL CLOCK
DRIVER TURBOCLOCK W
DESCRIPTION
The IDT5V9955 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 IDT5V9955 has sixteen programmable skew
outputs in eight banks of 2. The two separate PLLs allow the user to
independently control A and B banks. Skew is controlled by 3-level input
signals that may be hard-wired to appropriate HIGH-MID-LOW levels.
The feedback input allows divide-by-functionality from1 to 12 through
the use of the xDS[1:0] inputs. This provides the user with frequency
multiplication from1 to 12 without using divided outputs for feedback.
When the x
sOE
pin is held low, all the xbank outputs are synchronously
enabled. However, if x
sOE
is held high, all the xbank outputs except x2Q0
and x2Q1 are synchronously disabled. The xLOCK is high when the
xbank PLL has achieved phase lock.
Furthermore, when xPE is held high, all the outputs are synchronized
with the positive edge of the REF clock input. When xPE is held low, all the
xbank outputs are synchronized with the negative edge of REF. The
IDT5V9955 has LVTTL outputs with 12mA balanced drive outputs.
