Function
Laser select input.
When high, common cathode operation is selected; IBOUT_CC and SGND are functional
and internal 50Ω output terminations are switched in at the modulation outputs OUT+
and OUT-.
When low or floating, common anode operation is selected; IBOUT_CA and SV_CC are
functional and the 50Ω internal termination resistors at OUT+ and OUT- are
disconnected.

Automatic power control loop dominant pole capacitor. (Connect a capacitor between
this pin and V_CC3.)
A nominal capacitance of 2.2nF will give a bias current enable time of less than 1 ms.
