Pin Descriptions
Note: BCLK buffers cannot be supplied with 5 volts (Pins 14 and 20) if CPU
and fixed frequencies (Pins 1, 8 and 26) are being supplied with 3 volts.
PIN NUMBER
PIN NAME
TYPE
DESCRIPTION
8, 25
VDD
PWR
Power for logic, CPU and fixed frequency output buffers.
1X1
IN
XTAL or external reference frequency input. This input includes XTAL load
capacitance and feedback bias for a 10 - 30 MHz XTAL.
2
X2
OUT
XTAL output which includes XTAL load capacitance.
3
OEN
IN
OEN tristates all outputs when low. This input has an internal pull-up device.
4
BPIN
IN
Input to BPIN(0:5) buffers.
5
BHIN
IN
Input to BHIN(0:3) buffers.
11, 23
GND
PWR
Ground for logic, CPU and fixed frequency output buffers.
6, 7, 9, 10
BH(0:3)
OUT
Buffered copies of the BHIN input, typically used to drive the PCI device clock
inputs at one half the CPU frequency.
13, 12
FS(0:1)
IN
Frequency multiplier select pins. See table below. These inputs have internal pull-up
devices.
14, 20
VDD
PWR
Power for BCLK output buffers.
15, 16, 18 19,
21, 22
BP(0:5)
OUT
Buffered copies of the BPIN input, typically used to drive the host device clock
inputs at the CPU frequency. 17 VSS PWR Ground for BCLK output buffers.
24
CPU
OUT
The CPU output, which is a multiple of the input reference frequency as shown in
the table above. Duty cycle is 50/50±5% with a maximum frequency of 100 MHz.
26
24M
OUT
The 24M clock is fixed at 24 MHz.
28, 27
REF(0:1)
OUT
REF is a buffered copy of the crystal oscillator or reference input clock,
nominally 14.31818 MHz.
