Table 13 :
Crystal Parameters
Note:
Recommended Crystal: MELCOM 35.328MHz / UM1/ 30 / 30 / 0+70 / 15pF / FUND.
Typical specifications apply for VCC = 5.0V, temperature = 27°C, nominal process and bias current. Maximum and
minimum performance is with VCC ±5%, 0°C < T
ambient
< 70°C, and worst case process and bias current.
