Knowing that the 5G networks are going to dominate both Telecom and Datacom and more and more 5G base stations are under establishment, Nuvoton serves a total solution of Optical Transceiver from Fronthaul to Backhaul, or even from current optical transmission scenarios to new WDM (Wavelength Division Multiplexing) scenarios. For this new-coming WDM application, Nuvoton offers an MCU with built-in hardware Manchester Codec to implement the Pilot Tone Modulation for OAM data transmission.

The NuMicro M029G/ M030G/ M031G 32-bit microcontroller series is designed for Optical Transceiver Module applications, which have 3 major features for traditional one: (1) sensitive to the temperature, (2) small form factor and (3) an I²C interface for communication. As a result, both of the M030G and the M031G series have a built-in temperature sensor with ±2°C deviation from -40°C to 105°C, package selections of small size including QFN24 and QFN33, and 2 sets of strong I²C with 400K/1MHz slave mode and non-stretch mode.

Moreover, in upcoming WDM scenarios, “Pilot Tone Modulation”, is required. The Pilot Tone Modulation aims to add OAM data in the form of low-frequency dither into original signal to realize the OAM functions. Therefore, the M031G series, which supports Pilot Tone Modulation, is equipped with a Hardware Manchester Codec with CRC to encode and decode low-frequency dither signal and 1 set of DAC with “Auto Data Generation” function to generate the smooth sine waveform up to 500KHz for the output of Pilot Tone Modulation.

Whether you require the general optical transceiver or the one with Pilot Tone Modulation, you can find the most satisfied solution here in Nuvoton.
