Device Description A. General The MAX3639 is a highly flexible, precision phase-locked loop (PLL) clock generator optimized for the next generation of network equipment that demands low-jitter clock generation and distribution for robust high-speed data transmission. The device features subpicosecond jitter generation, excellent power-supply noise rejection, and pin-programmable LVDS/LVPECL output interfaces. The MAX3639 provides nine differential outputs and one LVCMOS output, divided into three banks. The frequency and output interface of each output bank can be individually programmed, making this device an ideal replacement for multiple crystal oscillators and clock distribution ICs on a system board, saving cost and space. This 3.3V IC is available in a 7mm x 7mm, 48-pin TQFN package and operates from -40°C to +85°C. Maxim Integrated Products. All rights reserved. Page 2 MAX3639 II. Manufacturing Information A.

Reliability Evaluation A. Accelerated Life Test The results of the 135°C biased (static) life test are shown in Table 1. Using these results, the Failure Rate ( ) is calculated as follows: = 1 MTTF = = 22.9 x 10 1.83 (Chi square value for MTTF upper limit) 192 x 4340 x 48 x 2 (where 4340 = Temperature Acceleration factor assuming an activation energy of 0.8eV) -9 = 22.9 F.I.T. (60% confidence level @ 25°C) The following failure rate represents data collected from Maxim’s reliability monitor program. Maxim performs quarterly life test monitors on its processes. This data is published in the Reliability Report found at http://www.maxim-ic.com/qa/reliability/monitor. Cumulative monitor data for the MB3 Process results in a FIT Rate of 0.08 @ 25C and 1.33 @ 55C (0.8 eV, 60% UCL) B. Moisture Resistance Tests The industry standard 85°C/85%RH or HAST testing is monitored per device process once a quarter. C. E.S.D. and Latch-Up Testing The HQ01 die type has been found to have all pins able to withstand a HBM transient pulse of +/- 2500V per JEDEC JESD22-A114. Latch-Up testing has shown that this device withstands a current of +/- 250mA and overvoltage per JEDEC JESD78. Maxim Integrated Products. All rights reserved.
