UTP (UNSHIELDED TWIST PAIRS) CABLES
The DS16EV5110A can be used to extend the length of UTP cables, such as Cat5, Cat5e and Cat6 to distances
greater than 20 meters at 1.65 Gbps with < 0.13 UI of jitter. Please note that for non-standard DVI/HDMI cables,
the user must ensure the clock-to-data channel skew requirements are met. Table 7 presents the recommended
boost control settings for various data rates and cable lengths for UTP configurations:
