Notes on Electrical Characteristics:
1
Guaranteed by design and characterization, not 100% tested in production.
2
Slew rate measured through Vswing centered around differential zero
3
Vxabs is defined as the voltage where CLK = CLK#
4
Only applies to the differential rising edge (CLK rising and CLK# falling)
Defined as the total variation of all crossing voltages of CLK rising and CLK# falling. Matching applies to rising edge rate of
CLK and falling edge of CLK#. It is measured using a +/-75mV window centered on the average cross point where CLK meets
CLK#. The average cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate
calculations
6
All Long Term Accuracy and Clock Period specifications are guaranteed assuming that REFOUT is at 14.31818MHz
5
7
Operation under these conditions is neither implied, nor guaranteed.
8
Maximum input voltage is not to exceed maximum VDD

How to Write:
How to Read:
Controller (host) sends a start bit.
Controller (host) sends the write address D2 (H)
ICS clock will acknowledge
Controller (host) sends the beginning byte location = N
ICS clock will acknowledge
Controller (host) sends the data byte count = X
ICS clock will acknowledge
Controller (host) starts sending Byte N through
Byte N + X -1
(see Note 2)
• ICS clock will acknowledge each byte one at a time
• Controller (host) sends a Stop bit
