JUST-IN-TIME OSCILLATORS
 JITO®-2
PACKAGE P
PLASTIC SURFACE MOUNT

The new JITO®-2 (Just In Time Oscillators) line represents Fox's latest contribution to helping buyers and engineers alike meet the increasing pressure of bringing new designs and products to market faster and more efficiently. This new line of crystal oscillators cuts the industry standard lead time of 10 weeks down to just 10 days or less for custom and standard frequency oscillators; 48 hours for evaluation units. Engineers need custom frequencies as quickly as possible to test and prove their prototypes. Production people need to know that custom frequency products can be accessed quickly without holding up their line. And buyers have to ensure that they can satisfy both engineering and production needs. The JITO®-2 line provides a total solution to those requirements by cutting industry standard lead times by an average of 90%.

Features
  • Custom and standard frequencies from 1.000 up to 250MHz
  • 100, 50, 30, 25, 20 PPM stability
  • 3.3 or 5 volts; -20 to 70ºC or -40 to +85ºC operating range
  • SMD package (same footprint as Epson 8002JA)
  • Fox quality built-in and test verified.
  • Enable/Disable option available.
• ELECTRICAL CHARACTERISTICS (Ta = 25ºC, CL = Max Load)

**** PECL can be programmed to 250 MHz; output terminations may have to be modified for desired output levels.  See Application Note "JITO-2 PECL Interface Considerations".

Application Precautions:  It is recommended that a sample be evaluated in each application before adding JITO®-2 or any other oscillator to the AVL.  This JITO®-2 series of products utilize PLL technology.  As a result, overall circuit jitter will often increase if applied to another PLL device.  Please contact Fox technical support if you require assistance.
