O Crystal output pin. Do Not Connect when using FIN
* Note: All bidirectional buffers (I/Os) incorporate an internal 60KΩ pull up resistor except when PDB mode is used. In
configurations that use PDB, the PDB pin will have a 10MΩ pull up resistor.
KEY PROGRAMMING PARAMETERS
CLK[ 0:4 ]
Output Frequency
Output Drive Strength
Programmable Input/Output
CLK[0]
FVCO2 / P
CLK[1]
FVCO1 / (P*(1,2,4,8)) or FREF / (P*(1,2,4,8))
CLK[2]
FREF / (P*(1,2,4,8))
CLK[3]
FVCO2 / (P*(1,2,4,8)) or FREF / (P*(1,2,4,8))
CLK[4]
FREF / P
Where FVCO = FREF * M / R
M = 11 bit
R = 8 bit
P = 5 bit (Odd/Even Divider)
Each output has
three optional drive
strengths to choose
from. They are:
 Low: 4mA
 Std: 8mA (default)
 High:16mA
Most pins are multi-function I/Os and can be
configured as:
 OEM – (Master OE controlling all outputs)
 CSEL – (Device Configuration Switching)
 PDB – (Power Down)
 CLK[0:4] – (Output)
 HiZ or Active Low disabled state
