ATA5749 [Preliminary]

10. Electrical Characteristics

VS = 1.9V to 3.6V Tamb = –40°C to +125°C, CLK_ON = “High”; DIV_CNTRL = “Low”, CLOAD_CLK = 10 pF. fXTO = 13.0000 MHz,

CLK = 1.625 MHz unless otherwise specified. If crystal parameters are important values correspond to a crystal with CM = 4.0 fF,

C0 = 1.5 pF, CLOAD = 9 pF and RM ≤ 170Ω. Typical values are given at VS = 3.0V and Tamb = 25°C

No.
