Description
The ICS8602 is a high performance, low skew, 1-to-9 Differential-to-LVCMOS/LVTTL Zero Delay Buffer and a member of the HiPerClockS? family of High Performance Clocks Solutions from IDT. The CLK, nCLK pair can accept most standard differential input levels. The VCO operates at a frequency range of 250MHz to 500MHz. The external feedback allows the device to achieve "zero delay" between the input clock and the output clocks. The device is designed only for 1:1 input/output frequency ratios. The output divider allows a wide input/output frequency range with the 250MHz to 500MHz VCO. The PLL_SEL pin can be used to bypass the PLL for system test and debug purposes. In bypass mode, the reference clock is routed around the PLL and into the internal output dividers.The low impedance LVCMOS/LVTTL outputs are designed to drive 50W series or parallel terminated transmission lines. The effective fanout can be doubled by utilizing the ability of the outputs to drive two series terminated lines. The differential reference clock input will accept any differential signal levels.
