The launch of the domestic "double Gigabit" action plan and the 145th Digital Economy Plan has promoted the construction of 10GPON ports and above from more than 5 million by the end of 2021 to 12 million by the end of 2025; The number of gigabit broadband users has also increased nearly tenfold to 60 million households. In terms of overseas markets, AT&T in North America plans to double its fiber coverage by the end of 2025. The agency predicts that as more operators use PON to support their access network strategies, the global PON device port will maintain a compound growth rate of 12.3%, and the penetration rate of 10GPON, 25G PON and 50G PON PON port schemes will reach 50%. The future of PON optical module market is broad.

Optical module special series SoC product features:

Two I2C modules that support slave multi-address mode, flexible configuration, high speed and high reliability; Suitable for different mainstream equipment manufacturers.
Internal digital modules (such as I2C and PWM) can map any IO port and support flexible port function allocation.
The PLU module with 4 built-in units can realize more complex logic functions.
The IO supports 5V tolerance, which meets the electrical requirements of the module for the port.
Provides up to 22-channel 12bit ADCs; 2/4-channel 12bit DAC.
Built-in factory-calibrated high precision temperature sensor.
Supports internal LDO 1.8V/2.4V output.
Available in QFN20(3mmx3mm), QFN24(3mmx3mm), QFN32(4mmx4mm) small size packages.
