General specification for HC49 family crystals
Low-cost, industry-standard crystal unit
Available to close tolerances
Frequency range 1.0MHz to 250MHz
Pakcage options
DESCRIPTION
HC49 crystals are long-established, industry-standard crystals.
Standard HC49 crystals provide a very low cost source of system
clock frequency and due to the dimensions of the crystal blank
employed, vthey are also able to be produced to very close
tolerances where required. Supply in several holder variants is
available
