1 Specified values are with PLL disabled. Timing vs. temperature and data valid keep out windows (that is, the minimum amount of time valid data must be presented to

the device to ensure proper sampling) are delineated in Table 28.

2 Measured from CSB rising edge when Register 0x00, Bit 4, is written from 1 to 0 with the VREF decoupling capacitor equal to 0.1 μF.
