Note 1:
All voltages are referenced to ground.
Note 2:
This is the absolute accuracy of the master oscillator frequency at the default settings.
Note 3:
This is the change that is observed in master oscillator frequency with changes in voltage from nominal voltage at
TA = +25°C.
Note 4:
This is the percentage frequency change from the +25°C frequency due to temperature at VCC = 3.3V.
Note 5:
The dither deviation of the master oscillator frequency is unidirectional and lower than the undithered frequency.
Note 6:
This indicates the time elapsed between power-up and the output becoming active. An on-chip delay is intentionally
introduced to allow the oscillator to stabilize. tstab is equivalent to approximately 512 master clock cycles and depends
on the programmed master oscillator frequency.
Note 7:
Output voltage swings may be impaired at high frequencies combined with high output loading.
Note 8:
A fast-mode device can be used in a standard-mode system, but the requirement tSU:DAT > 250ns must then be met. This
is automatically the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch
the LOW period of the SCL signal, it must output the next data bit to the SDA line at least tR MAX + tSU:DAT = 1000ns +
250ns = 1250ns before the SCL line is released.
Note 9:
After this period, the first clock pulse is generated.
Note 10:
A device must internally provide a hold time of at least 300ns for the SDA signal (referred to as the VIH MIN of the SCL sig-
nal) to bridge the undefined region of the falling edge of SCL.
Note 11:
The maximum tHD:DAT need only be met if the device does not stretch the LOW period (tLOW) of the SCL signal.
Note 12:
CB—total capacitance of one bus line, timing referenced to 0.9 x VCC and 0.1 x VCC.
Note 13:
Typical frequency shift due to aging is ±0.5%. Aging stressing includes Level 1 moisture reflow preconditioning (24hr
+125°C bake, 168hr 85°C/85%RH moisture soak, and 3 solder reflow passes +240 +0/-5°C peak) followed by 1000hr
max VCC biased 125°C HTOL, 1000 temperature cycles at -55°C to +125°C, and 168hr 121°C/2 ATM Steam/Unbiased
Autoclave.
