Transmitter & Receiver Details
The optical transmitter portion incorporates a 4-channel VCSEL (Vertical Cavity Surface Emitting Laser) array, a 4-channel input buffer, laser driver, diagnostic monitors, and control blocks. The control interface utilizes a Two Wire Serial (TWS) interface for clock and data signals.
The optical receiver portion incorporates a 4-channel PIN photodiode array, a 4-channel TIA array, and diagnostic monitors. Results for optical input power are available through the TWS interface. Alarm and warning thresholds are established for monitored attributes, with flags and interrupts generated when attributes fall outside defined thresholds.
