Low-Jitter, Wide Frequency Range,

Programmable Clock Generator with 10 Outputs

General Description

The MAX3637 is a highly flexible, precision phase-

locked loop (PLL) clock generator optimized for the next

generation of network equipment that demands low-jitter

clock generation and distribution for robust high-speed

data transmission. The device features subpicosecond

jitter generation, excellent power-supply noise rejection,

and pin-programmable LVDS/LVPECL output interfaces.

The MAX3637 provides nine differential outputs and

one LVCMOS output, divided into three banks. The fre-

quency and output interface of each output bank can be

individually programmed, making this device an ideal

replacement for multiple crystal oscillators and clock dis-

tribution ICs on a system board, saving cost and space.

This 3.3V IC is available in a 7mm x 7mm, 48-pin TQFN

package and operates from -40°C to +85°C.
