LHS980B-350D-002 is a small sized and high performance single-phase PLBus module for smart home devices. The module operates as a sub-node to communicate with Gateway (i.e., the master node) through power line. The module has UART port to interface with external host CPU, also has other I/O interfaces including PWM, GPIOs.

Features and Major Specifications:

• PLBus center carrier frequency: 350kHz (can be customized to operate at any
  frequency within 30 – 500 kHz, thus flexibly support CENELEC, FCC and China PLC band)
• Bandwidth: 48kHz
• Physical layer technology: OFDM modulation with zero-crossing transmission (Z-OFDM)
• Typical data rate: 5-10kbps (max data rate 20kbps, depending on operating environment)
• PLC signal interface: on-board line driver, for single phase, 50Hz (60Hz available), external PLC coupling transformer required
• Data interface: UART, default baud rate 9600bps (max 19200bps), 8 data bits, 1 stop-bit, even parity. Interface protocol: PLC-MCP 3.5 (by LME)
• Signal output level: ≤120dbuV @ 50Ω load
• DC power supply: +12VDC
• Static power consumption (receiving): ≤ 180mw
• Operating environment: -20℃～+85℃, relative humidity ≤ 95%
• Dimensions: 36mm(L)×15 mm(w)×12 mm(H)
