Product Description:
PI15011 is optimized for PON OLT and other EAM-based modules. It features a 12-bit current output digital-to-analog converter (IDAC) for laser bias current control
in the power feedback loop. It provides a TIA that converts MPD current to a 12-bit, 250KSPS analog-to-digital converter (ADC). The IDAC supports a full-scale output
range of 150mA with very low voltage drop. A buck DC-DC is used to provide the IDAC supply voltage and can adjust the output voltage to optimize power consumption.
A second IDAC can provide up to 250mA for applications requiring SOA bias.
EAM bias is provided by a 12-bit negative voltage output digital-to-analog converter (VDAC). The current of this DAC can be monitored through an ADC. The VDAC has
an output or input current capability of up to 60mA. A negative voltage DC-DC is used to provide the required power for the VDAC.
The ADC integrates a low-latency threshold comparator, making it suitable for monitoring solutions such as photodiodes (MPD), received signal strength indicators (RSSI),
and signal loss (LOS) detection. The ADC can also measure the voltage at the IDAC pins as well as the current generated or input by the VDAC, enabling optical power
monitoring.
The integrated TEC controller features register-controlled output voltage, digital circuit PID control, as well as monitoring and alarm functions.
