SRG,RSG Driver Circuit
Notes:
A. All values are in Ohms and Microfarads unless otherwise noted.
B. These circuits are implemented on TI's EVM285SPD with negative-swing.
C. In these circuits, line driver IC before AC couple should drive over 5.5V swing because of
certain switching for discrete MOS-FETs (TP2104,TN2106).
D. In these circuits, pre-driver line distance from line driver IC output to AC couple input
should keep as short as it can.
E. The EL7156CS (Intersil/Elantec) driver is an acceptable alternative to the discreet
SRG circuit shown.
