E3/DS3/STS-1 Example Circuit
Note 9: Pin names in ( ) denote pin names from 78P7200. Pin numbers refer to 28 PLCC package. Default
settings used to simulate 78P7200.
Note 10: Resistors on TCLK, TNEG, TPOS are optional but recommmeded. Clock pulse shapes at the inputs to
the 78P2241 are dependent on board layout and will dictate the need for such added resistors.
Note 11. Adding a series Ferrite Bead on VCC pins may be required for some pc board layout.
