This device, together with PIN diode and TIA preamplifier, can implement highly integrated, low cost, low power fiber optic receiver.
The receiver’s front-end loss-of-signal (LOS) detector circuit indicates when the input signal level falls below user-adjustable threshold. The LOS detect circuit has hysteresis to prevent chatter at the output.
The ADN2804 is available in a compact 5 x 5 mm, 32-lead LFCSP.
