Overview
The CDCLVD2102RGTR, produced by Texas Instruments, is a dual 1:2 differential clock buffer designed to distribute two clock inputs to a total of four pairs of differential LVDS (Low Voltage Differential Signaling) clock outputs. This device is optimized for low additive jitter and high-frequency clock distribution, making it suitable for various high-performance applications. The CDCLVD2102 operates within a 2.375–2.625V power supply range and is characterized over an industrial temperature range of –40°C to 85°C. It is packaged in a compact 16-pin, 3mm × 3mm QFN (Quad Flat No-Lead) package.
