VT98501

The VT98501 is a 3.3V CMOS, clock multiplier integrated circuit. The device provides an excellent quality high frequency output clock from a lower frequency crystal or clock input. Tri-level selection inputs S0 and S1 are used to select any one of nine multipliers, stored in the on-board ROM, and apply it to the input to produce the desired output. The resulting output includes many commonly used frequencies up to 160 MHz. Phase Locked Loop (PLL) technology allows the device to use an input signal from an inexpensive crystal.

When Output Enable (OE) is low, the clock output is in high impedance state. The VT98501, when used with an inexpensive crystal, provides a cost-effective clock source for most electronic systems.
