The IDT409 is a cost-effective clock synthesizer developed to optimize component count for PC peripheral applications. The device supports a common, low cost 14.31818 MHz crystal using an on-chip crystal oscillator. The device locks all output frequencies to enhance system performance. By supporting common PC peripheral interface frequencies including dual 25 MHz and 40/80 MHz frequencies the clock lowers chip count enhancing system cost and reliability. The IDT409 utilizes a low pin count 8-pin SOIC package to optimize board space. IDT provides a wide-range of low-jitter and power consumer application clock sources. These devices are capable of supporting CCD, video, audio, USB, CPU, and other peripherals.
