General Description

The MAX7393/MAX7394 precision silicon oscillators

replace crystals, ceramic resonators, and crystal oscillator

modules in systems with a +2.4V to +3.6V operating sup-

ply voltage range.

The MAX7393/MAX7394 consist of a temperature-com-

pensated precision oscillator with enable (MAX7394) or

autoenable (MAX7393). The MAX7393/MAX7394 are sup-

plied at specific frequencies, just like crystals and res-

onators. Output frequency accuracy is guaranteed to be

within ±0.25% (TDFN) and ±1.3% (µDFN) (0°C to +85°C)

and ±1.0% (TDFN) and ±1.8% (µDFN) over the -40°C to

+125°C temperature range.

The small size and robust operation of the MAX7393/

MAX7394 make them ideal for space-constrained or envi-

ronmentally demanding applications where high accura-

cy is required. The high accuracy of the MAX7393/

MAX7394 is ideal for use in USB applications, computers,

and white goods.

The MAX7393/MAX7394 are available in 6-pin, 3mm x

3mm TDFN and 2mm x 2mm µDFN packages. They are

specified for the -40°C to +125°C temperature range.

Note: The MAX7394 is available in factory-set frequencies from

922kHz to 48MHz. The MAX7393 is available in factory-set

frequencies from 922kHz to 20MHz. There are 10 standard

frequencies (see the Selector Guide) with a required 2.5k order

increment. Nonstandard frequencies are also available with a

required 10k order increment. For nonstandard versions,

contact factory for availability and ordering information.
