Common Cathode/Common Anode Configuration Control
When CC_SEL is programmed high, the M02094 is configured for common cathode lasers. When CC_SEL is low, the
M02094 is configured for common anode lasers.
The state of the CC_SEL pin determines:
1. whether bias current is sourced or sunk
2. whether monitor photodiode current is sunk or sourced
3. whether internal termination resistors at OUT+ and OUT- are active
4. whether the redundant safety switch disconnects VCC or GND from the output circuitry.
The affected pins are OUT+, OUT-, SV_CC/IB_OUTCC, and SGND/IB_OUTCA. The Table 3-2 below shows the configura-
tion of each pin for the 2 states of CC_SEL.
