Function
Laser select input.
When high, common cathode operation is selected; IBOUTCC 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; IBOUTCA and SVCC
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 VCC3.)
A nominal capacitance of 2.2nF will give a bias current enable time of less than 1
ms.
