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.

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.

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.
