HCMOS/TTL CRYSTAL OSCILLATOR SERIES HO-12/HO-22 DESCRIPTION VTM offer a very competitively priced range of full size (HO- 12) and half size (HO- 22) HCMOS / TTL Crystal oscillators. They are housed in a resistance welded case. The frequency range available is 1.000 to 100MHz. Output symmetry is 40 to 60% standard, although 45 to 55% is available. Likewise the standard operating temperature range is 0º C to 70º C, although an extended range of -40º C to +85º C can be manufactured.
