Input/Output

Where M = 8 bit

R = 5 bit

P = 14 bit

Three optional drive strengths to

choose from:

• Low: 4mA

• Std: 8mA (default)

• High: 16mA

One output pin can be configured as:

• OE - input

• FSEL - input

• PDB – input

This programmable I/O pin can be configured as an Output Enable (OE)

input, Power Down input (PDB) or On-the-Fly Frequency Switching

Selector (FSEL). This pin has an internal 60K

pull up resistor for OE,

PDB & FSEL.

The OE and PDB features can be programmed to allow the output to float

(Hi Z), or to operate in the ‘Active low’ mode.
