PLJ-8LED is a cost-effective frequency display component of 8-bit digital tube display. It is mainly used for the display of frequency values of transceiver and other equipment, and can also be used for conventional frequency measurement. This component has the characteristics of compact and delicate, reliable performance, good visual effect and low cost.   Features: With Microchip's PIC16F648A, 2.4 GHz frequency meter. Using temperature-compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO). Unique gate control and precise time algorithm (non-timed interrupt). Gate (display refresh) time 0.01 seconds / 0.1 seconds / 1.0 seconds, real-time display frequency value. Single-ended input design, three-channel frequency measurement (low channel / high channel / Auto Channel). Dual frequency design, value and IF / down mode can be preset separately. Using eight 0.56 inches high brightness digital display, eight adjustable brightness. Circuit is simple and reasonable structure,
