ASV-12.000MHZ-EJ-T is a 3.3Vdc HCMOS SMD crystal clock oscillator designed for precision timing applications. The device operates at a 12 MHz frequency with an overall frequency stability of ±20 ppm (based on the "J" option code), operating temperature range of -20°C to +70°C (option "E"), and supply voltage of 3.3V ± 10%. It features a tri-state enable/disable function with typical enable time of 3.5 ms and disable time of 100 ns, along with a maximum output load of 15 pF and output voltage specifications of 0.9 × Vdd (high) and 0.4V (low). The hermetically sealed, seam-sealed package assures high reliability and is RoHS/RoHS II compliant, making it suitable for clock signaling in microprocessors, PC motherboards, and graphic cards where stable, low-jitter timing is essential.
