MAX24510EXG2

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX24510EXG2 is a high-performance clock multiplier and synthesizer IC featuring two independent Analog Phase-Locked Loops (APLLs) and ten differential output clocks. It supports any-to-any frequency conversion, accepting input frequencies from 9.72MHz to 750MHz and generating outputs up to 750MHz. The device utilizes internal EEPROM for automatic self-configuration upon power-up or reset. Key electrical specifications include an operating temperature range of -40°C to +85°C and dual voltage supplies of 1.8V and 3.3V. Output jitter performance is typically 0.18 to 0.3ps RMS for integer multiplication and 0.25 to 0.4ps RMS for fractional multiplication within the 12kHz to 20MHz integration band.

• Automatic self-configuration at power-up from internal non-volatile EEPROM memory
• Supports CML, LVDS, LVPECL, HSTL, SSTL, and HCSL output interfacing

Clock Generators, PLLs, Frequency Synthesizers Applications

• Frequency synthesis for Ethernet standards including 25MHz, 125MHz, and 156.25MHz
• Synchronous Ethernet clock generation and SONET/SDH frequency conversion
• PCIe-compliant clock generation for Gen 1, 2, and 3 interfaces
• Clock distribution for microprocessors, ASICs, and FPGAs

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the ordering suffix '2' corresponds to the lead-free and RoHS-compliant package variant as specified in the manufacturer's documentation. Confirm the specific pin-package configuration matches the 81-CSBGA requirement for the target design. Ensure compatibility with the required SPI interface protocol for register access and configuration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the MAX24510EXG2 when ten independent output clocks are required, distinguishing it from the five-output MAX24505 variant. Evaluate the need for sub-picosecond jitter performance suitable for high-speed serial links. Consider the availability of internal EEPROM for boot-time configuration versus external programming requirements. Verify that the input source can support the differential or single-ended formats supported by the IC1, IC2, and IC3 pins.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the MAX245xx family of flexible clock multipliers and synthesizers manufactured by Microchip Technology. It shares architectural similarities with the MAX244xx series but integrates internal EEPROM for autonomous initialization. The device is designed for telecommunications and high-performance computing applications requiring precise timing signals with minimal phase noise.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The MAX24505EXG2 serves as a functional substitute if only five output clocks are required, sharing identical core APLL architecture and packaging. Cross-referencing with the MAX24410EXG2 may be necessary for designs not requiring internal EEPROM storage, though register maps and pinouts should be verified for compatibility.
