This device, together with PIN diode and TIA preamplifier, can implement highly integrated, low cost, low power fiber optic receiver.
The receiver front end, loss of signal (LOS) detector circuit indicates when the input signal level has fallen below user-adjustable threshold. The LOS detect circuit has hysteresis to prevent chatter at the output.
The ADN2812 is available in compact 5 x 5 mm 32-lead lead frame chip scale package (LFCSP).
