High-performance clock generators

4 October 2006 Analogue, Mixed Signal, LSI

Maxim's MAX9450/1/2 series of high-performance clock generators is available with three types of outputs: LVPECL (MAX9450), LVDS (MAX9451), and HSTL (MAX9452). By integrating the VCXO, PLL, buffer, and clock source, the MAX945x clock generators save cost and space over a discrete solution. The devices also have redundant inputs, perfect for applications that require holdover if an input fails.

The MAX945x series accepts inputs from 8 kHz to 500 MHz, and drives outputs up to 160 MHz. The devices also feature clock output jitter less than 0,8 ps r.m.s. in a 12 kHz to 20 MHz band. These low-jitter, high-performance clock generators ensure reliability in the system and jitter performance, making them ideal for SONET and SDH data-communications systems and base-station applications.

The MAX945x devices operate from a 2,4 V to 3,6 V supply over -40 to 85°C and come in 32-pin TQFP packages with exposed paddles.
