The IDT411 is a cost-effective clock synthesizer developed to optimize component count for PC motherboard and peripheral applications. The device supports a common, low cost 14.31818 MHz crystal. The device locks all output frequencies to enhance system performance. By supporting common PC peripheral interface frequencies including 25 MHz for Ethernet and 24.576 MHz for audio and other applications, the device lowers chip count enhancing system cost and reliability. The IDT411 utilizes a low pin count 8-pin SOIC package to optimize board space. IDT is a leader in low jitter and power consumer application clock sources. These devices are capable of supporting CCD, video, audio, USB, CPU, and other peripherals.
