8P791208NLGI8

Clock Buffers, Drivers Overview

The 8P791208NLGI8 is a low additive jitter 2:8 clock buffer manufactured by Renesas Electronics. It accepts input frequencies ranging from 1Hz to 700MHz and generates up to eight outputs. The device features two differential inputs supporting LVPECL, LVDS, LVHSTL, HCSL, or LVCMOS reference clocks. Outputs are arranged in two banks of four, each with independent power supply support for 3.3V, 2.5V, or 1.8V. Output types include LVPECL, LVDS, or dual LVCMOS. Key electrical parameters include a maximum output frequency of 700 MHz, a maximum propagation delay of 2.25 ns, and an operating voltage range of 1.71 V to 3.465 V.

Clock Buffers, Drivers Feature Summary

• Low additive jitter performance with an output noise floor of –158dBc/Hz @ 156.25MHz
• Supports two differential inputs and up to eight outputs (LVPECL, LVDS, or LVCMOS)
• Two independent output banks with separate power supply capabilities
• Pin-selectable input-to-output routing controlled by 3.3V-tolerant pins

Clock Buffers, Drivers Applications

• High-speed data communication systems requiring precise clock distribution
• Telecommunications infrastructure equipment
• Test and measurement instruments
• Industrial automation control systems

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix '8' against official Renesas documentation to confirm package or tape-and-reel configuration differences compared to standard tray versions. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure compatibility with existing board layout constraints for the VFQFN-32 package.

Clock Buffers, Drivers Selection Notes

Select this component when low phase noise and flexible output drive strengths are required. Verify that the application supports the 700MHz maximum frequency limit. Ensure the design accommodates the separate power domains for the two output banks if using mixed voltage levels like 3.3V and 1.8V simultaneously.

Clock Buffers, Drivers Part Context

This part belongs to the 8P791208 series of low additive jitter buffers. It serves as a direct replacement for legacy clock distribution solutions requiring high fan-out with minimal jitter degradation. The device integrates pin-selectable functionality to reduce bill-of-materials complexity by supporting multiple input/output standards in a single package.
