STMicroelectronics ST7570 S-FSK Power Line Networking System-on-Chip Datasheet
The ST7570 is a powerful power line networking system-on-chip designed for smart metering, street lighting control, and command and control networking. It combines a high-performance PHY processor core with a protocol controller core and a fully integrated analog front end (AFE) to provide a cost-effective single-chip solution based on the IEC61334-5-1 S-FSK standard.
The device features a programmable bit rate up to 2.4 Kbps, signal-to-noise ratio estimation, and received signal strength indication. The fully integrated analog front end includes an ADC, DAC, PGA with automatic gain control, and a high linearity modulated signal generator. It also incorporates a single-ended power amplifier capable of delivering up to 1 A rms output current.
