Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These
ratings are stress specifications only and functional operation of the device at these or any other conditions above those
listed in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect product reliability.
The
ICS95V860
is able to track Spread Spectrum Clock (SSC) for reduced EMI.
The
ICS95V860
is an I
2
C slave/receiver that supports standard and "fast" mode. The
ICS95V860
I
2
C interface is
compliant to "The I2C-Bus Specification", version 2.1 January 2000 Philips Semiconductors, except that I2C_SDA
and I2C_SCL are not 5.0V tolerant, but have a maximum input voltage of 4.2V or V
DDI2C
+ 0.6V, whichever is
lower. Register bits control the enable for each output pair and a global enable bit (GLOBALEN#) disables all
outputs except the feeback output pair. A low places the disabled output pair in a high impedance state. Outputs
are active during power up and are guaranteed to be at the correct duty cycle and period after the clock
stabilization time.
