Abstract

This application note shows how TI's LMK6Bx BAW oscillator provides ultra-low jitter reference clocking for LMKDB1x LP-HCSL and LMK1Dx LVDS clock buffers. The LMK6Bx delivers 9.3fs of RMS jitter at 625MHz HS-LVDS, enabling multiple clean clock outputs for telecommunications, networking, and data center applications. The document includes termination schemes, performance data, and phase noise analysis for oscillator-buffer combinations, supporting PCIe Gen 7 and other high-speed digital requirements.
