EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE TCXO HCMOS 7 x 5 x 2.5mm SMD, 'V' Group EMV57T Series
DESCRIPTION
Miniature 7 x 5 x 2.5mm SMD package Wide frequency range: 27.0MHz to 200.0MHz Supply voltage 3.3 Volts Frequency stability from ±1ppm over -30 to +75°C RoHS compliant EMV57T series TCXOs are packaged in a miniature 4 pad ceramic SMD package. With squarewave (CMOS) output, tolerances are available from ±1.0ppm over -30° to +75°C. The part has a 0.01mF decoupling capacitor built in. EMV57T - OUTLINES AND DIMENSIONS Temp.
