AMC60804T SLASF79 – JANUARY 2023 AMC60804T 4-Channel Optical Monitor and Controller With Current and Voltage Output DACs and Multichannel ADC 1 Features 3 Description • The AMC60804T is a highly integrated, low-power analog monitor and controller for optical transceiver applications. • • • • • • Four 12-bit current output DACs (IDACs) – 200-mA full-scale output range – Low supply headroom: 200 mV at 200 mA Four 12-bit voltage output DACs (VDACs) – Selectable full-scale output ranges: –5 V, –2.5 V, +2.5 V and +5 V – High-current drive capability: ±50 mA Multichannel, 12-bit, 1-MSPS SAR ADC – Four external inputs: 2.5-V and 5-V ranges – Four IDAC voltage monitor channels – Four VDAC current monitor channels – Programmable sequencer – Programmable out-of-range alarms Internal 2.5-V reference Supply and temperature fault alarms SPI and I2C interfaces: 1.7-V to 3.6-V operation – SPI: 4-wire interface – I2C: Four target addresses Specified temperature range: –40°C to +125°C The AMC60804T includes four 12-bit current output digital-to-analog converters (IDACs) and four 12-bit voltage output DACs (VDACs) with programmable output ranges. The device also includes a 12-bit, 1-MSPS analog-to-digital converter (ADC) used for external and internal signal monitoring, supply and temperature alarm monitors, and a high-precision internal reference. The AMC60804T 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 optical modulators. Additionally, the AMC60804T IDACs support a fullscale output range of 200 mA with very-low power dissipation. The IDACs eliminate the need for external components to bias laser diodes. In combination, the AMC60804T four VDACs and four IDACs enable accurate biasing of electro-absorption modulated lasers. 2 Applications • • Optical module Intra-DC interconnect (metro) AMC60804T Supply and Temperature Monitors IDAC Channels 1–4 SPI or I2C Serial Interface IDAC1 Voltage Monitors IDAC IDAC2 IDAC3 IDAC4 ×4 VDAC Channels 1–4 Interrupt Control and Alarm Detector VDAC1 Current Monitors VDAC VDAC2 VDAC3 VDAC4 ×4 The AMC60804T also includes four input pins that are multiplexed to the ADC and incorporate a lowlatency window comparator. These features make 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 these outputs to be monitored. The AMC60804T low power, high integration, very small size, and wide operating temperature range make this device an excellent choice as an all-in-one control circuit for optical modules.

Some language may be different than what you would expect to see for certain technology areas. 4.1.1 Related Documentation For related documentation, see the following: AMC60304EVM user's guide 4.2 Trademarks All trademarks are the property of their respective owners. 4.3 Electrostatic Discharge Caution This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 4.4 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions. 5 Mechanical, Packaging, and Orderable Information The following pages include mechanical, packaging, and orderable information.
