13.2.1.2 Formula for the Source Resistance
The relative resistance Rs
13.2.1.3 Calculating the Effective Source Resistance
13.2.1.3.1 Wiring Resistance
Wiring and bonding adds a constant offset to the driver resistance, that is relevant if TX1 and TX2 are
switched to low impedance.
13.2.1.3.2 Effective Resistance
The source resistances of the driver transistors found in the Product Information Field (see 6.2) are
measured at production test with GsModCW set to 01
