Note 1: Minimum high or low time of input clock.
Note 2: For the 1.544 MHz and 2.048 MHz output selections, the input to output clock skew is not
controlled nor predictable and will change between power up cycles. Because it is dependent on the phase
relationship between the output and feedback divider states following power up, the input to output clock
skew will remain stable during a given power up cycle. If controlled input to output skew is desired for this
output clock frequency please refer to the MK2049 or MK2069 products.
Note 3: Input reference is the 8 kHz output from a Mitel/Zarlink MT9045 device in freerun mode
(SEL2:0 = 100, 19.44 MHz external crystal).
