Product Description

PI15016/11 is a highly integrated, low power, analog monitoring and control solution with a comprehensive set of integrated TEC, Buck, and negative voltage DC-DC.

It supports various optoelectronic module controller applications without the need for external circuits, reducing costs and PCB area to the maximum extent.

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

power feedback loops. It provides TIA conversion for 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. The Buck DC-DC is used to provide the IDAC supply voltage and allows adjustable output voltage for power optimization. A second

IDAC can provide up to 250mA of voltage for applications requiring SOA bias.

EAM bias is provided by a 12-bit negative voltage output DAC (VDAC). The current of this DAC can be monitored through an ADC. The output or input current of the VDAC

can reach 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 photodiodes (MPD), received signal strength indicators (RSSI), and signal loss (LOS)

detection solutions. The ADC can also measure the voltage of the IDAC pins and the current output or input from 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.

PI15016 includes all the features of PI15011 but also adds support for dual SOA and dual LD/EAM modules through additional IDACs and VDACs. Two IDACs can support a

bias of 250mA for SOA.
