Device Description A. General The MAX3679 is a low-jitter precision clock generator with the integration of three LVPECL and one LVCMOS outputs optimized for Ethernet applications. The device integrates a crystal oscillator and a phase-locked loop (PLL) clock multiplier to generate high-frequency clock outputs for Ethernet applications. Maxim's proprietary PLL design features ultra-low jitter (0.36psRMS) and excellent power-supply noise rejection, minimizing design risk for network equipment. Maxim Integrated Products.

Reliability Evaluation A. Accelerated Life Test The results of the 135C biased (static) life test are shown in Table 1. Using these results, the Failure Rate ( ) is calculated as follows: = 1 MTTF = 1.83 192 x 4340 x 47 x 2 (Chi square value for MTTF upper limit) (where 4340 = Temperature Acceleration factor assuming an activation energy of 0.8eV) -9 = 22.8 x 10 = 22.8 F.I.T. (60% confidence level @ 25C) The following failure rate represents data collected from Maxim's reliability monitor program. Maxim performs quarterly 1000 hour life test monitors on its processes. This data is published in the Product Reliability Report found at http://www.maxim-ic.com/. Current monitor data for the MB3HT Process results in a FIT Rate of 0.7 @ 25C and 11.5 @ 55C (0.8 eV, 60% UCL) B. Moisture Resistance Tests The industry standard 85C/85%RH or HAST testing is monitored per device process once a quarter. C. E.S.D. and Latch-Up Testing The HD86 die type has been found to have all pins able to withstand a HBM transient pulse of +/-1500 V per JEDEC JESD22-A114-D. Latch-Up testing has shown that this device withstands a current of +/-250 mA. Maxim Integrated Products. All rights reserved.
