Crystal Pin 1:
This pin should be connected to one side of a 20MHz (
±
50 ppm) crystal.
ALG
Crystal Pin 2:
This pin should be connected to the other side of a 20MHz (
±
50 ppm)
crystal.
ALG
Bandgap Voltage Reference:
Connect a 6.20_K
, 1% resistor between this pin and the BGGND pin to
provide an accurate current reference for the DM9801.
ALG
Bandgap Voltage Reference Return:
Return pin for the 6.20_K
resistor connection.
I
Test Mode Control Pin:
TSTMODE=0: Normal operating mode.
TSTMODE=1: Enable test mode.
No Connect:
These pins are reserved. Leave these pins unconnected (floating).
