Note 1:
Stresses beyond those listed under Absolute Maximum Ratings the LTC6930 family of parts are defined as follows: may cause permanent damage to the device. Exposure to any Absolute LTC6930-4.19 fNOM = 4.194304MHz Maximum Rating condition for extended periods may affect device LTC6930-5.00 f reliability and lifetime. NOM = 5.000000MHz LTC6930-7.37 f
Note 2:
LTC6930C is guaranteed functional over the operating range of NOM = 7.372800MHz –40°C to 85°C. LTC6930-8.00 fNOM = 8.000000MHz
Note 3:
The LTC6930C is guaranteed to meet specified performance from LTC6930-8.19 fNOM = 8.192000MHz 0°C to 70°C. The LTC6930C is designed, characterized and expected to
Note 5:
Long-term drift of silicon oscillators is primarily due to the meet specified performance from –40°C to 85°C but is not tested or QA movement of ions and impurities within the silicon and is tested at 30°C sampled at these temperatures. The LTC6930I is guaranteed to meet under otherwise nominal operating conditions. Long-term drift is specified specified performance from –40°C to 85°C. The LTC6930H is guaranteed as ppm/√kHr due to the typically non-linear nature of the drift. To calculate to meet specified performance from –40°C to 125°C. The LTC6930MP is drift for a set time period, translate that time into thousands of hours, guaranteed to meet specified performance from –55°C to 125°C. take the square root and multiply by the typical drift number. For instance,
Note 4:
Frequency accuracy and frequency drift are defined as deviation a year is 8.77kHr and would yield a drift of 89ppm at 30ppm/√kHr. Drift from the nominal frequency or the nominal frequency divided by the without power applied to the device may be approximated as 1/10th of the integer set through the DIV pins for each part. The nominal frequency for drift with power, or 3ppm/√kHr for a 30ppm/√kHr device. 6930fe For more information www.linear.com/LTC6930 5 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information AC Electrical Characteristics DC Electrical Characteristics Timing Characteristics Pin Functions Applications Information Package Description Revision History Related Parts
