MAX7393/MAX7394
Precision Silicon Oscillators with
Enable or Autoenable
General Description
Features
The MAX7393/MAX7394 precision silicon oscillators
replace crystals, ceramic resonators, and crystal oscilla-
tor modules in systems with a +2.4V to +3.6V operating
supply voltage range.
● ±0.25% (TDFN) and ±1.3% (μDFN) Total Accuracy
for 0°C to +85°C
● ±1.0% (TDFN) and ±1.8% (μDFN) Total Accuracy for
-40°C to +125°C
The MAX7393/MAX7394 consist of a temperature-com-
pensated precision oscillator with enable (MAX7394) or
autoenable (MAX7393). The MAX7393/MAX7394 are
supplied 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.
● Resistant to Humidity and Vibration
● 12mA Operating Current (48MHz Version)
● 5ns Output Rise/Fall Time
● 40% to 60% Maximum Duty Cycle
● No External Components Required
● +2.4V to +3.6V Operation
The small size and robust operation of the MAX7393/
MAX7394 make them ideal for space-constrained or envi-
ronmentally demanding applications where high accu-
racy is required. The high accuracy of the MAX7393/
MAX7394 is ideal for use in USB applications, computers,
and white goods.
● Available Factory-Set Frequencies from 922kHz to
48MHz
● Space-Saving TDFN and μDFN Surface-Mount
Packages
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,
