Overview
The MC100LVEP111FAR2, produced by ON Semiconductor, is a high-performance 2:1:10 differential clock driver designed for low skew clock distribution. This device is optimized for use in high-speed clock distribution applications, accepting two clock sources into an input multiplexer. It operates in PECL (Positive ECL), NECL (Negative ECL), and HSTL (High-Speed Transceiver Logic) modes, making it versatile for various system requirements.
The MC100LVEP111FAR2 is particularly suited for applications where tight skew control is critical, such as in backplane or board-level clock distribution. Its design ensures minimal skew within the device and between devices, enhancing the overall system performance and reliability.
