Overview

The 8732-01 is a low voltage, low skew, 3.3V LVPECL Clock Generator. The 8732-01 has two selectable clock inputs. The CLK0, nCLK0 pair can accept most standard differential input levels. The single ended clock input accepts LVCMOS or LVTTL input levels. The 8732-01 has a fully integrated PLL along with frequency configurable outputs. An external feedbackinput and outputs regenerate clocks with "zero delay". The 8732-01 has multiple divide select pins for each bank of outputs along with 3 independent feedback divide select pins allowing the 8732-01 to function both as a frequency multiplier and divider. The PLL_SEL input can be usedto bypass the PLL for test and system debug purposes.In bypass mode, the input clock is routed around the PLLand into the internal output dividers.
