TDA7427D Overview
As a clock IC, PLLs is packaged using the Tube method. This clock generator is embedded in the 20-SOIC (0.295, 7.50mm Width) package. 20 terminations can be found in frequency synthesizer. Basically, a voltage of 5V should be applied to this electronic frequency generator. Clock, Crystal is designed as this clock generator's input. 1 circuits are implemented to access the electronic component's full performance. This clock-based frequency generator provides a frequency up to 290MHz Max. This component can be conveniently installed on the panel thanks to the Surface Mount. The maximal supply voltage this clock generator would take is 5.5V. The supply voltage for this frequency synthesizer should be kept above 4.5V for safety considerations. Clock PLL works with 4.5V~11V supply voltage provided. The ambient temperature should be set at -40°C~85°C, which is estimated by the test statistics. This is a clock generator compatible with Clock, Crystal logic levels. This electronic component can be classified as a PLL Frequency Synthesizer. This clock-generating IC is a 20-bit device designed explicitly for microprocessors. According to the base part number TDA7427, its related parts can be found. There is an available 20 pin on the clock generators.
