DOCSIS 4.0 DOWNSTREAM PERFORMANCE

8× OFDM channels, 20 dB virtual tilt from 258 MHz to 1794 MHz, and 6 dB offset at 1026 MHz. In Figure 7 to Figure 10, the performance at

lower output powers is limited by the test equipment and is not indicative of the noise performance of the device. Results are not corrected

for system contributions. Using the downstream schematic and bill of materials (BOM) per the Recommended Applications Circuit and BOM

section. VDD = 21 V, IDD = 540 mA, TPADDLE = 35°C, and ZS = ZL = 75 Ω, unless otherwise noted.
