Electrical Tests Application Circuit devices should processed with observation these guidelines. Before assembled soldered circuit boards tested, remove shorting rings. sockets integrated circuits must conducting voltage when individual devices assembled circuit boards inserted withdrawn, unless works specifications state otherwise. Ensure that test devices power supplies produce voltage spikes, either when being turned normal operation power fuse blows other fuses respond. When supplying bipolar integrated circuits with current, negative voltage GND) first connected. general, interruption this potential during operation permissible. Signal voltages only applied inputs when better after supply voltage turned They must disconnected when better before supply voltage turned off. Power supplies integrated circuits blocked near possible supply terminals With bipolar recommended low-inductance electrolytic capacitor least paralleled ceramic capacitor example. Using with high output currents, necessary value electrolytic capacitor must adapted test application circuit. Transient behavior dynamic output resistance power supplies, line inductances supply load circuit particular inductive loads motors have considered. When switching line inductances inducitve loads, stored power consumed externally, unless otherwise specified (e.g. electrolytic capacitor, diodes, Z-diodes power supply). Also switching supply voltage prior load rejection should taken into account. with low-pass character output stages (e.g. drivers PNP/NPN endstages), normally need additional external compensation output. This applies particularly complex loads. output power amplifiers compensated Boucherot element. individual cases, bridge circuits only need capacitance bypassing load. Depending application however, also recommended connect capacitor from each output ground. Observe notes instructions respective data books.

Better protection obtained with bags conducitve polyethylene foam (e.g. RCAS 1200 from Richmond Redlands, California). should always ensure that different boards cannot touch. special cases necessary provide protection against strong electric fields, such generated conveyor belts example. this purpose sheath aluminium foil recommended, although direct contact between film must avoided.

General Information
In-Process Control During Production manufacturing integrated circuits comprises several hundred production steps. each step executed with utmost accuracy, in-procress control outstanding importance. Some processes require more than hundred different test measures. tests have been arranged manner that individual steps process reproduced continuously. decreasing failure rates reflect persistent effort this direction; course years they have been reduced considerably despite immense rise complexity.
Reliability Monitoring general course failure rate versus time shown so-called "bathtub" curve. failure rate peak during first operating hours (early failure period). After early failure period decayed, "constant" failure rate period starts during which failures occur approximately uniform rate. This period ends with repeated rise curve during wear-out failure period. ICs, however, latter period usually lies beyond service life specified individual equipment. Reliability tests usually destructive examinations. They are, therefore, carried with samples. Most failure mechanisms accelerated means higher temperatures. temperature dependence failure mechanisms, possible simulate future operational behavior within short time applying high temperatures; this called life test. acceleration factor life test obtained from Arrhenius equation
where temperature which life test performed, assumed operating temperature, Boltzmann constant. Important factor activation energy lies between differs considerably individual failure mechanisms. Siemens ICs, reliability data gained from life tests converted operating temperature assuming average activation energy acceleration factor life tests thus compared with operational behavior. This method also considers failure mechanisms with activation energy, i.e. which only slightly accelerated temperature effect. Various reliability tests periodically performed with types that representative certain production line this described brochure "Quality Assurance-Integrated Circuits". Such tests e.g. humidity test relative humidity, pressure cooker test, well life tests 1000 hours more. Test results available form summary reports.

Usual implementation uses ports interface subscriber line leading large amount wiring and, thus, problems such crosstalk large board size. Usual implementation also characterized fixed adjustment line interface conditions although telephone line conditions vary considerably with national standards even with subscriber line installations.

SICOFI provides separate input output ports transmit receive direction. Transmit Direction analog input signal converted, digitally filtered transmitted either PCM-encoded linear. converter used modified slope adaptive interpolative sigma-delta modulator with sampling rate kHz. remove resulting noise, antialiasing done with order Sallen-Key prefilter (PREFI). Subsequently signal downsampled decimation filters together with bandpass filters (LPX, HP). Receive Direction digital input signal received PCM-encoded linear, digitally filtered converted generate analog output signal. Digital interpolation done lowpass filter (LPR) interpolation filters Converter output order Sallen-Key postfilter (POFI). Programmable Function high flexibility SICOFI based variety user programmable filters, which analog gain adjustment AGX, digital gain adjustment frequency response adjustment impedance matching filter transhybrid balancing filter gain optimum result within given environment while observing existing prescriptions, Siemens offers SICOFI user software packet 2060, which performs calculation filter coefficients using overall optimizing approach. Because modularity SICOFI software program, possible SICOFI together with transformer SLICs with series transverse feeding fixed electronic SLICs (see chapter 9.2: Available SICOFI SLIC Documentation) user specific SLICs 2060 software runs IBM-AT compatible under MS-DOS Version later providing Kbyte available RAM, Mbyte floppy disk drive, math coprocessor 80297 (optional). purpose following pages given overview SICOFI software background. more details SICOFI hardware, refer SICOFI data sheets. list available SICOFI software hardware tools will found chapter 9.2.

REF.BYT optional input file SICOFI program. reference file which defines frame which program write calculated coefficients with some predefined commands. These commands macrocommands necessary send SICOFI coefficients from Peripheral Board Controller (PEB 2050) SICOFI (PEB 2060) means SLD-bus control byte. After calculation actual SICOFI coefficients stored output file called e.g. USER.BYT. This file contains commands from REF.BYT file together with updated coefficients. SICOFI.CTL control file SICOFI program. contains data controlling optimization simulation processes. SICOFI.BAT SICOFI batch program which starts execution program generate SICOFI coefficients calculate theoretical transfer functions SLIC-SICOFI. RESULT.RES output file SICOFI.BAT. contains coefficients programming SICOFI according SLIC used. calculated results corresponding various measurements taken SICOFI SLIC listed. (e.g. return loss, frequency response, echo return loss, etc.). This result file also used control file SICOFI.BAT.
