| EURO QUARTZ 8 pin DIL, hermetically-sealed package Wide frequency range: 27.0MHz to 200.0MHz Supply voltage 3.3 Volts Frequency stability from 1ppm over -30 to +75C EMV8T Series TCXO HCMOS 8 pin DIL, 'V' Group EMV8T - OUTLINES AND DIMENSIONS DESCRIPTION EMV8T series TCXOs are packaged in an 8 pin DIL hermetically sealed package. With squarewave (CMOS) output, tolerances are available from 1.0ppm over -30 to +75C. The part has a 0.01mF decoupling capacitor built in.
