DESCRIPTION:
3.3V LVPECL clock generator-divider. It has two selectable clock inputs. The
CLK/ xCLK pair can accept most standard differential input levels. The PCLK/
xPCLK pair can accept LVPECL, CML, or SSTL input levels. The clock enable
is internally synchronized to eliminate runt pulses on the outputs during
asynchronous assertion/deassertion of the clock enable pin.
01 ideal for those applications that demand well-defined performance and
repeatability.
The IDT85304-01 is a low skew, high performance 1-to-5 differential-to-
Guaranteed output and part-to-part skew characteristics make the IDT85304-
