input reference of 25MHz. The input reference may be derived
from an external source or by the addition of a 25MHz crystal to
the on-chip crystal oscillator. An external reference may be applied
to the XTAL_IN pin with the XTAL_OUT pin left floating.
The device offers spread spectrum clock output for reduced EMI
applications. An I
spread spectrum operation as well as select either a down spread
value of -0.35% or -0.5%.
The ICS841S02I is available in both standard and lead-free
20-Lead TSSOP packages.
