MAX9450EHJ

Overview

The MAX9450EHJ is a voltage-controlled crystal oscillator (VCXO) based clock driver from the 9450 series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.4V to 3.6V and supports frequencies up to 160MHz. The device features differential input and output capabilities, accepting LVCMOS, LVDS, or LVPECL inputs while providing LVPECL outputs. Packaged in a 32-TQFP with an exposed pad (5x5 mm), it is designed for applications requiring precise clock distribution in 3G, Ethernet, and SONET/SDH systems.

Feature Summary

PLL-based clock driver supporting VCXO functionality
Differential input/output configuration
Input compatibility with LVCMOS, LVDS, and LVPECL signals
LVPECL output drive capability

Applications

3G wireless infrastructure
Ethernet networking equipment
SONET/SDH transmission systems

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated against official component documentation. Confirm the package specification matches the 32-TQFP Exposed Pad (5x5 mm) form factor. Ensure the operating temperature range meets requirements for -40°C to 85°C industrial standards. Cross-reference the 9450 series classification to validate functional parameters.

Selection Notes

Select this component when a PLL-based clock driver with VCXO characteristics is required for high-frequency signal integrity. The 160MHz maximum frequency and differential I/O make it suitable for sensitive timing applications. Verify that the 2.4V to 3.6V supply voltage aligns with the system power architecture. Ensure the 32-TQFP package fits the PCB layout constraints.

Part Context

This part belongs to the 9450 series of clock drivers, specifically designed for telecommunications and data communication markets. It integrates phase-locked loop technology to manage clock jitter and skew, essential for maintaining synchronization in high-speed serial links like SONET/SDH and Ethernet interfaces.
