Downstream All Digital Channel Plan, 190×, ITU-T J.83B, Single-Channel Quadrature Amplitude

Modulation (SCQAM) 6 MHz Channels, 54 MHz to 1218 MHz

See the application circuit in Figure 39. VDD = 8.0 V, IDD = 470 mA, TPADDLE = 35 °C, and ZS = ZL = 75 Ω, unless otherwise noted.

NOISE POWER RATIO1

NPR

10 dB tilt, TCP = 68 dBmV

0 dB tilt, TCP = 68 dBmV

1 The noise power ratio gives an equivalent result to the standard MER testing but with improved dynamic range using an industry-accepted method.
