ASM5I961P

The ASM5I961P is a 2.5V or 3.3V compatible, 1:18 PLL based zero delay buffer. With output frequencies of up to 200MHz, output skews of 150pS the device meets the needs of the most demanding clock tree applications.

The ASM5I961P is offered with two different input configurations. That offers an LVCMOS reference clock while it offers an LVPECL reference clock.

When pulled high the OE pin will force all of the outputs (except QFB) into a high impedance state. Because the OE pin does not affect the QFB output, down stream clocks can be disabled without the internal PLL losing lock.

The ASM5I961P is fully 2.5V or 3.3V compatible and requires no external loop filter components. All control inputs accept LVCMOS compatible levels and the outputs provide low impedance LVCMOS outputs capable of driving terminated 50 transmission lines. For series terminated lines the ASM5I961P can drive two lines per output giving the device an effective fanout of 1:36. The device is packaged in a 32 lead LQFP package to provide the optimum combination of board density and performance.
