DESCRIPTION

PTN1111
The PTN1111 is a low-skew, 1:10 PECL clock distribution device.
One selected clock signal out of two selectable inputs is fanned out
to 10 identical, precision time-aligned differential outputs.
ST00011
PIN DESCRIPTION
The PTN1111 is provided with a VBB reference voltage to allow for
single-ended PECL input and with complementary clock inputs to
allow for differential PECL input.
PIN NUMBER
The main purpose and benefit of the PTN1111 is low skew: between
individual outputs of a single PTN1111 (within-part skew or
output-to-output skew) as well as measured from part-to-part.
Within-part skew is realized by careful attention to internal layout
and design of the PTN1111, whereas part-to-part skew is achieved
by control and monitoring of relevant process parameters.
The PTN1111 can be used for high-performance, high-speed clock
distribution in systems which utilize PECL as the primary signaling
standard. Designers can take advantage of the device’s performance
to distribute clocks across a board or backplane, at an extremely high
degree of time alignment, thereby affording system processors to
achieve maximum utilization of the clock cycle.
