MX8335
GENERAL DESCRIPTION
The MX8335 is a clock synthesizer chip for Rambus
channel. With an advanced phase locked loop technol-
ogy, the MX8335 provides two clock outputs (CLKOUT)
with frequency ranging from 200MHz to 267MHz. The
desired high speed clock is the 40/3 Multiplication ratio
of a reference input clock. The reference clock could
be supplied by an external crystal ranging from 15MHz
to 20MHz.
