| CA3420AS/3 CA3420AS/3 PDF The AD1857/AD1858 are complete single-chip stereo digital audio playback components. They each comprise an advanced digital interpolation filter, a revolutionary linearity-compensated multibit sigma-delta (∆) modulator with dither, a jitter-tolerant DAC, switched capacitor and continuous time analog filters and analog output drive circuitry. Other features include digital de-emphasis processing and mute. The AD1857/AD1858 support continuously variable sample rates with essentially linear phase response, and support 50/15 µs digital de-emphasis intended for Redbook 44.1 kHz sample frequency playback from Compact Discs. The user must provide a master clock that is synchronous with the left/right clock at 256 or 384 times the intended sample frequency. CA3420AS/3 Datasheet page of the EEPROM is repeatedly transmitted back to the reader by the IC after the command has completed. This permits a verify function for the commands. For the Write Lock and Write Config commands, the entire contents of page 8 are transmitted. Between each frame transmitted, there is a listening window of 8 bit-times to synchro- nize the reader and/or permit the reader/writer to issue a new command to the IC. The listening window will begin immediately following the transmission of the appropriate EOT (see Data Communications section for information regarding EOT). CA3420AS/3 Suppliers DATA POLLING: The AT49BV/LV080 features DATA polling to indicate the end of a program cycle. During a program cycle an attempted read of the last byte loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been completed, true data is valid on all outputs and the next cycle may begin. DATA polling may begin at any time during the program cycle. CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADM8840 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. The NC7WZ38 is a dual 2-Input NAND Gate with open drain output stage from Fairchilds Ultra High Speed Series of TinyLogic. The device is fabricated with advanced CMOS technology to achieve ultra high speed with high output drive while maintaining low static power dissipation over a very broad VCC operating range. The device is specified to operate over the 1.65V to 5.5V VCC range. The inputs and output are high impedance when VCC is 0V. Inputs tolerate voltages up to 7V independent of VCC oper- ating voltage. The open drain output stage will tolerate volt- ages up to 7V independent of VCC when in the high impedance state. accompanying wiring and circuits must be kept insulated and dry to avoid leakage and corrosion. This is especially true if the circuit may operate at cold temperatures where condensa- tion can occur. Printed-circuit coatings and varnishes such as Humiseal and epoxy paint or dips can be used to ensure that moisture cannot corrode the FM20 or its connections.
