NOTE 1: ALL RESISTOR VALUES ARE ±1%.
NOTE 2: S IS A SIDACTOR.
NOTE 3: THE FUSES ARE OPTIONAL TO PREVENT AC POWER LINE CROSSES FROM COMPROMISING THE TRANSFORMERS.
NOTE 4: THE RT RESISTORS ARE USED TO INCREASE THE TRANSMITTER RETURN LOSS (Table 7-A). NO RETURN LOSS IS REQUIRED
FOR T1 APPLICATIONS.
NOTE 5: THE 68
F IS USED TO KEEP THE LOCAL POWER PLANE POTENTIAL WITHIN TOLERANCE DURING A SURGE.
NOTE 6: REFER TO APPLICATION NOTE 324 FOR SIDACTOR AND FUSE DETAILS.
