The YIC 20.00M-SMDXT324 is a precision quartz crystal oscillator packaged in a 4-pad, 2.0mm x 1.6mm SMD (Surface Mount Device) ceramic package. Internally, it consists of a quartz crystal, a temperature-compensated oscillator (TCXO) circuit, and a buffer amplifier. Its frequency stability is typically 20 ppm over the operating temperature range of -20°C to +70°C, and it operates from an input voltage of 3.3V. It has a low current consumption of 8.5mA, a high frequency stability of 50 ppm at higher temperatures, and a load capacitance of 10pF. It has four-pad connections with no external components required, meaning it is easy to install. Furthermore, it is RoHS/WEEE compliant and guaranteed to meet tight frequency specifications.
