VT98501S1X - Vaishali Semiconductor

VT98501S1X 3.3V Low Phase Noise Clock Multiplier

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 resul.
