ELECTRICAL SPECIFICATIONS
(continued)
The output power spectrum meets the spectral mask of Figure 8 – HomePNA PSD Mask with a termination of 100
ohms and back-to-back Ethernet packets of 1518 bytes length with random data. The resolution bandwidth shall
be 100 kHz. The specified PSD levels include thermal noise. The power level requirements below 1.1 MHz allow
1M8 PHY stations to interoperate with G.dmt and G.lite modems.
Two power operating modes are defined, LOW_POWER and HIGH_POWER. The maximum Power Spectral
Density (PSD) levels for the modes are defined in Figure 8 – HomePNA PSD Mask. For applications interfacing to
the PSTN, the power levels of FCC Part 68 shall not be exceeded
