New Product Release - PI14010

      The PI14010 is a highly integrated, low-power, analog, monitoring and control solution with a comprehensive set of integrated TEC, Buck and Inverting DC-DC regulators. A wide variety of optical transceiver controller applications are supported without need of external circuitry, thereby minimizing cost and PCB area.

   The PI14010 has four 12-bit current output digital-to-analog converters (IDACs) and four 12-bit voltage output DACs (VDACs) with programmable output ranges. A 12-bit, 250KSPS analog-to-digital converter (ADC) is used for external and internal signal monitoring A temperature alarm monitor and a high precision internal reference that eliminates the need of an external reference in most applications.

     The PI14010 VDACs support both positive and negative output range operation and are capable or sourcing and sinking up to 60mA. Additionally, the IDACs support a programmable full-scale output ranges of 150mA/250mA with very low power dissipation.

     The PI14010 includes four voltage input pins and up to eight current input pins with a programable TIA gain. These inputs are multiplexed to the ADC and incorporate a low-latency window comparator, making them suitable solutions for monitor photo diode (MPD), received signal strength indicator (RSSI) and loss-of- signal (LOS) detection. The ADC is also capable of measuring the voltage at the IDAC pins as well as the current being sourced or sunk by the VDACs, thus enabling power monitoring of these outputs.
