Functional Description
The CY7B9911V 3.3V RoboClock+ High Speed Low
Voltage Programmable Skew Clock Buffer (LVPSCB) offers
user selectable control over system clock functions. These
multiple output clock drivers provide the system integrator with
functions necessary to optimize the timing of high perfor-
mance computer systems. Each of the eight individual drivers,
arranged in four pairs of user controllable outputs, can drive
terminated transmission lines with impedances as low as 50
Ω
.
They deliver minimal and specified output skews and full swing logic
levels (LVTTL).
Each output is hardwired to one of nine delay or function
configurations. Delay increments of 0.7 to 1.5 ns are deter-
mined by the operating frequency with outputs that can skew
up to ±6 time units from their nominal “zero” skew position. The
completely integrated PLL allows external load and cancels
the transmission line delay effects. When this “zero delay”
capability of the LVPSCB is combined with the selectable
output skew functions, you can create output-to-output delays
of up to ±12 time units.
Divide-by-two and divide-by-four output functions are provided
for additional flexibility in designing complex clock systems.
When combined with the internal PLL, these divide functions
allow distribution of a low frequency clock that are multiplied
by two or four at the clock destination. This facility minimizes
clock distribution difficulty enabling maximum system clock
speed and flexibility.
