8523BGLF

Overview

The 8523BGLF is a clock buffer and driver manufactured by Renesas Electronics Corporation. It features a 2:4 input-to-output ratio with LVDS outputs, supporting a maximum frequency of 650 MHz. The device operates on a supply voltage ranging from 3.135 V to 3.465 V and functions within a temperature range of 0°C to +70°C. It is housed in a 20-TSSOP package (0.173", 4.40mm width) designed for surface mount installation.

Feature Summary

• Provides fan-out buffering and distribution capabilities for clock signals
• Supports differential LVDS output signaling
• Accepts multiple input formats including CML, HCSL, LVDS, LVHSTL, LVPECL, and SSTL

Applications

• Clock distribution networks requiring signal fan-out
• High-speed digital systems utilizing LVDS interfaces
• Telecommunications equipment timing architectures

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variations such as tube quantities. Ensure the operating temperature grade matches application requirements before finalizing procurement orders.

Selection Notes

Select this component when a 2:4 fan-out buffer with LVDS outputs is required. Verify that the system supports the specified input signal standards like CML or LVPECL. Ensure the design accommodates the 3.135V to 3.465V supply voltage range and the 20-TSSOP footprint constraints.

Part Context

This part belongs to the 8523B series of clock buffers. It shares architectural similarities with variants like the 8543BGLF and 8545BGLF, differing primarily in maximum frequency specifications and input/output configurations. These components are designed for precise timing distribution in complex electronic systems.

Replacement Considerations

Public confirmed substitute part numbers include 8543BGLF and 8545BGLF. Note that these alternatives may have different maximum frequency ratings or input compatibility profiles compared to the 8523BGLF.
