The ICS501 LOCOTM is the most cost effective way to generate a high quality, high frequency clock output from a lower frequency crystal or clock input. The name LOCO stands for LOw Cost Oscillator, as it is designed to replace crystal oscillators in most electronic systems. Using PhaseLocked-Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 160 MHz.
