83115BRLF

Overview

The Renesas Electronics 83115BRLF is a low skew, 1-to-16 LVCMOS/LVTTL fanout buffer. It operates with a single-ended clock input accepting LVCMOS or LVTTL signals. The device provides a 1:16 output ratio and supports frequencies up to 200 MHz. It functions on a core voltage of 3.3 V. Additive phase jitter is typically 90 fs (0.09 ps) RMS. The component is housed in a 28-pin QSOP package with dimensions of 9.9 x 3.8 x 1.47 mm and a pitch of 0.64 mm. Operating temperature ranges from 0°C to 70°C.

Feature Summary

• Provides 1-to-16 fanout distribution for clock signals
• Accepts LVCMOS or LVTTL single-ended inputs
• Features low skew performance for precise timing

Applications

• Clock distribution in high-speed digital systems
• Buffering LVCMOS/LVTTL clock sources
