O
Serial Clock.
Serial Data/Serial E
2
PROM Detection. During a reset operation,
the W9967CF samples this signal to see if an external E
2
PROM
exists. A 10K ohm pull-up resistor should be used if an external
E
2
PROM is used; otherwise it should be tied to VSS.

Description
XIN
11
Reference frequency input from a crystal or a clock source. It
should be 48 Mhz if PLL is off (PLLSEL = 0) or 12 Mhz if PLL is
on (PLLSEL = 1) for full-speed device.
XOUT
12
O
Oscillator output to a crystal. This pin is left unconnected if an
external clock source is employed.
