78Q2132
1/10BASE-TX
HomePNA/Ethernet Transceiver
HomePNA Transmitter
The normalized transmitter output waveform is shown in Figure 6 – HomePNA Transmit Pulse Shape and must
be measured directly at the transmitter terminated with 100 ohms. The waveform is bounded by the values of
TX_PEAK_V ±15%. The waveform has been normalized to the peak value of the envelope TX_PEAK_V, which is
specified in the transmit levels table for both HIGH and LOW power level options.
The maximum values of the waveform after 1 usec from when it first crosses the 5 mV threshold does not exceed
the mask of Figure 6 – HomePNA Transmit mask for times greater than 1usec.
HPNA TX Mask 7.5 Mhz
