The IDT85304-01 is a low-tilt, high-performance 1-to-5 difference-to-3.3V LVPECL clock generator - voltage divider. It has two optional clock inputs. CLK/ xCLK pairs can accept most standard differential input levels.
Schematic diagram
PCLK/ xPCLK pairs can accept LVPECL, CML, or SSTL input levels. Clock enablement is internally synchronized to eliminate small pulses on the output during asynchronous assertion/undo assertion of the clock enablement pin. The guaranteed output and partial to partial tilt characteristics make the IDT85304-01 ideal for those applications requiring good performance and repeatability
