XRK79892 Datasheet PDF - Exar Corporation

GENERAL DESCRIPTION
The XRK79892 is a PLL clock driver designed specifically for redundant clock tree designs. The device receives two differential LVPECL clock signals from which it generates 5 new differential LVPECL clock outputs. Two of the output pairs regenerate the input signals frequency and phase while the other
three pairs generate 4x, phase aligned clock outputs. External PLL feedback is used to also provide zero
delay buffer performance.
