Description

The ICS1493A-19 is a low cost frequency generator used for automotive application. Using patented Phase-Locked-Loop (PLL) techniques, the device uses a 19.35 MHz fundamental crystal source to produce seven clock outputs and one reference clock output. The output clocks are at 12.288 MHz, 14.7456 MHz, 22.5792 MHz, 48 MHz, 66.60 MHz, and 33.30 MHz with a 19.35 MHz reference clock output. The 66.60 MHz and 33.30 MHz clocks have a spread select option. Operating voltage of the ICS1493A-19 is 3.3 V.
