8525BGLF

Overview

The Renesas Electronics Corporation 8525BGLF is a clock buffer and multiplexer integrated circuit designed for high-speed signal distribution. It features a 1:4 input-to-output ratio, supporting a maximum operating frequency of 650 MHz. The device accepts differential CML or LVDS inputs and provides four differential LVPECL outputs. It operates within a supply voltage range of 3.135 V to 3.465 V and is housed in a 20-TSSOP package with a width of 4.40 mm. The component is rated for an industrial operating temperature range of 0°C to 70°C.

Feature Summary

• Supports 1:4 fan-out buffering and multiplexing functions
• Maximum operating frequency of 650 MHz
• Accepts differential CML or LVDS input signals
• Provides four differential LVPECL output channels

Applications

• High-speed data acquisition systems
• Telecommunications infrastructure equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'GLF' against current manufacturer documentation to confirm RoHS compliance status and lead times, as availability may vary by region. Confirm that the 20-TSSOP package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a single differential source must drive four distinct LVPECL loads at frequencies up to 650 MHz. Ensure the system power supply can maintain the required 3.135 V to 3.465 V range. Verify that the input signal format matches either CML or LVDS standards to ensure proper logic level compatibility.

Part Context

This part belongs to the ICS8525B family of clock buffers manufactured by Renesas Electronics. These devices are engineered for low jitter performance and are commonly used in digital signal processing applications requiring precise clock distribution. The GLF designation indicates a lead-free finish compliant with specific environmental directives.

Replacement Considerations

Consult official Renesas cross-reference tools for verified pin-compatible alternatives. Generic substitutes may not match the specific 650 MHz frequency limit or LVPECL output characteristics.
