SCHEMATIC
Schematics of transmitter. The supply domains are decoupled via a central lowpass filter (L3/C5) and individual filters for each domain (L1/C1,
L2/C2, L4/C6, L5/C9, L6/C10). The data is AC coupled via C4 and C7, and terminated by R8. The set resistors for the optical “0” (R2), optical “1”
(R3), alarm low level (R4) and alarm high level (R5) are connected to the VCC_R domain. The LA output is connected to the cathode of the laser
(P2-2). The LAQ output is terminated with a dummy load (R9) to the supply of the laser (VCC_LAS to P2-3, Laser anode). The bias current flows
via a 1206 shape resistor (R6, 1206 shape) for impedance increment of the bias source and removal of unnecessary power dissipation out of the
IC. An equalization or pulse shape filter is foreseen as C8/R10. The bandgap voltage is decoupled with C12. The input of the monitor current
(MONIN) must ‘see’ 30 to 50 pF. Therefore an additional capacitor is placed at its input. All components are 0603 shape, except R6 (power
dissipation) and C5 (value).
