3 Applications Information
This section provides general usage information for the design and implementation of the 73S8014R. The
documents listed in Related Documentation provide more detailed information.
3.1 Example 73S8014R Schematics
Figure 3 shows a typical application schematic for the implementation of the 73S8014R. Note that minor changes
may occur to the reference material from time to time and the reader is encouraged to contact Teridian for the
latest information.

CLKDIV2_from_uC
CLK track should be routed
far from RST, I/O, C4 and
C8.
NOTES:
1) VDD = 2.7V to 5.5V DC.
2) VPC = 4.75V to 5.5V DC
3) Required if external clock from uP is used.
4) Required if crystal is used.
Y1, C2 and C3 must be removed if external clock is used.
5) R1 and R3 are external resistors that adjust the VDD
fault voltage. Can be left open.
