Diodes Incorporated PI6C591200x LVPECL Fanout Buffers

Diodes Inc. PI6C591200x LVPECL Fanout Buffers are designed to distribute high-speed, low-jitter clock signals in demanding networking, telecommunications, and high-frequency computing applications. Available in 4-output (PI6C5912004), 6-output (PI6C5912006), and 8-output (PI6C5912008) configurations, these devices support output frequencies up to 2GHz and feature dual selectable reference inputs that accept single-ended or differential LVPECL, LVDS, HCSL, and CML clock sources. The buffers deliver ultra-low additive phase jitter of less than 40fs typical, low output skew, and fast propagation delays, helping to maintain signal integrity across multiple clock domains.

Operating from a 2.5V or 3.3V supply, the Diodes Inc. PI6C591200x family delivers reliable LVPECL clock distribution with low skew and consistent performance across industrial temperatures from -40°C to +85°C. Providing selectable inputs and compatibility with LVPECL, LVDS, HCSL, and CML signaling, these fanout buffers enable high-speed clock signal routing throughout networking, telecom, and computing platforms. Available in compact, RoHS-compliant packages, the PI6C591200x devices help designers expand clock distribution paths while maintaining the low jitter and signal integrity needed in high-performance systems.
