8T39S04ANBGI8

Clock Buffers, Drivers Overview

The Renesas 8T39S04ANBGI8 is a high-performance clock fanout buffer and multiplexer designed for distributing low phase-noise clock signals. It features two differential reference clock input pairs that accept LVPECL, LVDS, HCSL, HSTL, or single-ended crystal oscillator interfaces with frequencies up to 2 GHz. The device provides eight differential outputs configurable as LVPECL, LVDS, or HCSL, alongside one single-ended reference output with synchronous enable. Operating from dual supply voltages of 2.375V–2.625V or 3.135V–3.465V, it ensures low additive jitter and precise skew characteristics within an industrial temperature range of -40°C to +85°C.
