IDIC models need to know the type and origin of the integrated circuit block. TV, audio, video and other integrated circuits integrated circuits as its model or mark printed on the front, so you can know the initial prefix or sign depending on the model it is that the factory or company Atmel semiconductor integrated circuit, according to Its digital circuit functions can know is what kind. For example AN5620, AN prefix instructions are Panasonic bipolar integrated circuits, the number "5620" before the two main features distinguish the circuit, "56" note is TV with integrated circuits, while 70 to 76 belong to the audio aspects of the use of 30 ~ 39 genera VCR circuit. For details, please refer to the part of the production plant integrated model named, but to explain, in practical applications appear A4100 Central Standing Committee, in the end part of Hitachi HA, Sanyo LA, Japan and Japan's electricity with BA, Toshiba TA, TAA Sony CXA, Philips, Moto Rola other countries, TCA, TDA, of which product? In general, the prefix letters on behalf of the manufacturer omitted integrated way, usually make their name or trademark of the manufacturer or company printed up, as marked SONY, indicating that the integrated model is CXA1034, if marked SANYO, description Japan's Sanyo LA4100 Atmel, C1350C generally printed with NEC, indicating that the IC is manufactured uPC1350C NEC IC. 3362W-1-104 IC and lead away from the pulse voltage source should be set as far away from the location of pulsed high voltage integrated circuits, high-frequency devices. Integrated circuits and associated connecting lead wires as short as possible, in the inevitable long-term electricity 路爱特梅尔 to join overvoltage companies, especially automotive tape recorders installed should pay more attention. When the CMOS circuit wiring, external components should be connected as close to the pin, and strive to lead the short 捷爱特梅尔 electronic components, avoid using long leads in parallel, or easy to introduce a large distributed capacitance and inductance, easy to form LC oscillation. The solution is to train people in the input side 10KΩ resistor. When CMOS circuits for high-speed, pay attention to the circuit structure and PCB design. Output lead is too long, prone to "ring" phenomenon. Cause waveform distortion. Due to belong to the high-speed ECL digital integrated circuits, it is necessary to consider the "crosstalk" and other special problems exist in the signal line "reflection" and between adjacent signal lines, if necessary using transmission lines (such as coaxial cable), and to ensure that the transmission line impedance matching. In addition, the need to adopt some shielding, isolation measures. When operating frequency exceeding 200Mz, should use multi-layer circuit board to reduce ground impedance.
