XTLP

A
Crystal Positive/Negative
To use the internal oscillator, connect a 25 MHz crystal across
XTLP and XTLN. To use of an external clock, XTLN is grounded
and XTLP is driven with a 25 MHz clock.
Provides timing reference for all media dependant interface
operations. An internal PLL is used to multiply this clock by four
for use as the main system clock in internal clock mode.
XTLN
88
BUSCLK
15
I
Peripheral Clock
The source for the main system clock in external clock mode. In
synchronous bus mode, all host bus signals are assumed to be
synchronous to this clock.
