CRYSTAL CHARACTERISTICS
Note 1: All parameters are 100% tested at TA = +25°C. Limits over temperature are guaranteed by design and characterization and
not production tested.
Note 2: ICC is specified with DOUT open, CS = DIN = GND, SCLK = 4MHz at VCC = +5V; SCLK = 1MHz at VCC = +2.0V.
Note 3: Timekeeping current is specified with CS = VCC, SCLK = DIN = GND, DOSF = 0, EGFIL = 1.
Note 4: Guaranteed by design and not 100% production tested.
Note 5: All values referred to VIH(MIN) and VIL(MAX) levels.
