6V49205APAGI8

Overview

The 6V49205APAGI8 is a programmable clock generator featuring four internal phase-locked loops (PLLs) and integrated non-volatile EEPROM for configuration storage. It supports an input frequency range of 1 MHz to 200 MHz and generates output frequencies from 4.9 kHz to 500 MHz. The device accommodates various I/O standards, including LVPECL, LVDS, HCSL, and LVCMOS. It operates on a 3.3 V core supply voltage within an industrial temperature range of -40 °C to +85 °C. The component utilizes a fast 400 kHz mode I²C serial interface for programming and includes features such as programmable slew rate control, loop bandwidth adjustment, and redundant clock inputs with automatic or manual switchover capabilities.

Feature Summary

• Four individually programmable internal PLLs enable the generation of unique non-integer-related output frequencies from a single reference clock.
• Integrated non-volatile EEPROM allows for in-system configuration saving and restoration via a fast I²C serial interface.
• Supports multiple differential and single-ended output standards, including LVPECL, LVDS, HCSL, and LVCMOS, with programmable slew rate control.
• Features redundant clock inputs with automatic and manual switchover options to ensure continuous operation during input signal loss.

Applications

• High-performance data communications systems
• Telecommunications infrastructure equipment
• Consumer electronics requiring precise timing
• Networking applications

Procurement Notes

Verify the specific suffix 'PAGI8' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with the required I/O voltage levels and output standards for the target application. Confirm that the I²C address and EEPROM configuration requirements align with the system design. Check for any recent lifecycle status updates or recommended replacements for this specific part number.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single reference source. The integrated EEPROM simplifies board design by removing the need for external configuration memory. Consider the available output drive strengths and standards (LVPECL, LVDS, etc.) to match downstream logic families. Verify that the input frequency range covers the available reference clocks and that the power supply constraints fit the system architecture.

Part Context

This device belongs to the family of programmable clock generators designed for versatile timing solutions. It integrates multiple PLLs and non-volatile memory to provide flexible frequency synthesis without external configuration components. The inclusion of redundant inputs and hitless switching enhances system reliability in critical applications. It serves as a central timing hub for complex digital systems requiring diverse clock domains.

Replacement Considerations

Consult official Renesas documentation for direct pin-to-pin or functionally equivalent alternatives. Verify that any substitute part maintains the same package dimensions, pinout, and electrical characteristics. Ensure the replacement supports the required I/O standards and operating temperature range. Cross-reference the feature set to confirm adequate PLL count and memory capacity.
