Low-Jitter, Wide Frequency Range,
Programmable Clock Generator with 10 Outputs
MAX3638
General Description
The MAX3638 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 MAX3638 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.
