Complementary outputs optional. -5.2 Vdc 5% <45 mA to 110 MHz <70 mA above 110 MHz CO-437E: 1 ppm Output taken directly from 100K, ECLinPS or ECLinPS Lite gate, depending on temperature and frequency range. Complementary outputs optional. -4.5 Vdc5% at <60 mA CO-457E: 1 ppm CO-457 Supply Accuracy (at 25C) Temperature Stability Improved accuracy/stability available on some models. For example, for 7 ppm over 0C to +50C and for 10ppm over 0C to +70C. Improvement is also available over wider temperature ranges. Please contact factory. E= set to 1 ppm via external capacitor (< MHz in CO-432 and <240MHz in CO-434/37 package) STANDARD: 0C Option 1: Option 2: Option 5: Option 6: Option 7: to +70C: 25 ppm 50 ppm 5 ppm 10 ppm -55C to +85C: 0C 0C to +50C: to +50C: -55C to +125C: 50 ppm -55C to +125C: 100 ppm 3 ppm first year <2 ppm/year thereafter Aging Rate (typical after 30 days) 3 ppm first year 2 ppm/year thereafter top of page www..com http://www.vectron.com/products/xo/CO-437_457.htm 3/11/2009 Vectron Products - ECL/PECL Clock Oscillators - CO-437, CO-457 Page 2 of 3 SCREEN TESTING OF ABOVE MODELS Standard SCREEN TEST Stabilization Bake (150C) Seal Test (Gross and Fine) Temperature Cycling (Thermal Shock) Burn-in, operating 160 hours @125C Acceleration (5000g in Y1 axis) MIL-STD-883 METHOD -- 1014, Cond A2 1010, Cond B -- 2001, Cond A CLASS X X X Options CLASS D X X X X CLASS B X X X X X CLASS S Class S screen test requirements include 24 hour additional bake-out, 80 hour additional burn-in, thermal shock, PIND test and radiographic inspection in addition to Class B Screening.
