Description

The AMC60804 is a highly integrated, low-power analog monitor and controller optimized for electro-absorption modulated lasers (EML). The AMC60804 includes four 12-bit current output digital-to-analog converters (IDACs) and four 12-bit voltage output DACs (VDACs) with programmable output ranges. The AMC60804 also includes a 12-bit, 1-MSPS analog-to-digital converter (ADC) used for external signal and internal signal monitoring, supply and temperature alarm monitors, and a high-precision internal reference. The AMC60804 VDACs support both positive and negative output range operation and are capable or sourcing and sinking up to 50 mA, making them an excellent choice for biasing the electro-absorption modulator (EAM) in an EML. Additionally, the AMC60804 IDACs support a full-scale output range of 150 mA with very low power dissipation, thus eliminating the need for external components to bias the EML laser diode. In combination the AMC60804 four VDACs and four IDACs enable accurate biasing of up to four EML lasers. The AMC60804 includes four input pins that are multiplexed to the ADC and incorporate a low-latency window comparator, making this device an excellent choice for 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 sinked by the VDACs, thus enabling monitoring of these outputs. The AMC60804 low power, high integration, very small size, and wide operating temperature range make the device an excellent choice as an all-in-one, low-cost control circuit for the EML lasers found in optical modules.
