Block Diagram & Pin Configuration
Description
ThePI90LV211implementslowvoltagedifferentialsignaling(LVDS)
to achieve clocking rates as high as 320 MHz with low skew. The
PI90LV211isalowskew1:6fanoutdevicedesignedexplicitlyforlow
skew clock distribution applications. The device features a multi-
plexed clock input to allow for the distribution of a lower speed scan
or test clock with the high-speed system clock. When LOW the SEL
pin will select the differential clock input.
Both a common enable and individual output enables are provided.
When asserted the positive output will go LOW on the next negative
transition of the CLK (or SCLK) input. The enable function is
synchronous so that the outputs will only be enabled/disabled when
they are already in the LOW state. This avoids any chance of
generating a runt clock pulse when the device is enabled/disabled
as can happen with an asynchronous control. The internal flip flop
is clocked on the falling edge of the input clock, therefore all
associated specification limits are referenced to the negative edge
of the clock input.
Individual synchronous enable controls and multiplexed clock in-
puts make this device ideal as the first level distribution unit in a
distribution tree. The individual enables could be used to allow for the
disabling of individual cards on a backplane in fault tolerant designs.
