Basic 1: Understand HDBaseT Signal Characteristics High speed and high frequency HDMI 1.4 10.2 Gbps HDBaseT 1.0 300 MHz clock (PAM 16 encoding) Like 10GBaseT Ethernet and with similar Alien Crosstalk issues These AV signals look exactly like the data signals we encounter every day they are just a little less forgiving HDBaseT is packet based like Ethernet HDBaseT 1.0 is without a re-transmission mechanism - no recovery from packet errors especially evident with video HDBaseT 2.0 improves on this somewhat with a error recovery mechanism HDBaseT cannot be transmitted on an Ethernet network or through Ethernet switches HDBaseT over IP announced February 7 th at ISE
Basic 1: Understand HDBaseT Signal Characteristics HDBaseT is a digital signal Unlike an analog signal there is no gradual degradation of the signal Errors caused by excessive distance or Alien Crosstalk interference build quickly causing complete loss of signal
Basic 2: Consider the Application and Environment What distance and capabilities do you need? HDBaseT 1.0 Class A supports all 5Play features up to 100m Use extenders with Ethernet ports to send IP to a WAP or to a smart display Leviton resolution capability 1080p 36 bit deep color at 60Hz and VESA resolutions up to 1920 X 1200 at 60Hz up to 100m (328 ft) Class A: 100m with Ethernet Channel 4K UHD up to 2160p 24 bit true color at 30Hz with 4K chroma subsampling color palette 4:2:2 up to 60m (197 ft)
Basic 2: Consider the Application and Environment HDBaseT 1.0 Class B Supports up to 70m distance More cost effective Where Ethernet functionality is not required Leviton resolution capability Class B: 70m No Ethernet Channel 1080p 36 bit deep color at 60Hz and VESA resolutions up to 1920 x 1200 at 60Hz up to 70m (230 ft) 4K ultra high definition up to 2160p 24 bit true color at 30Hz with 4K chroma subsampling color palette 4:2:2 up to 40m (131 ft)
Basic 2: Consider the Application and Environment HDBaseT 2.0 Three New Classes Class C 4K 60Hz @ 100m (Cat 6A cable) USB 2.0 Class D 1080p 60Hz @ 30m (Cat 6A cable) USB 2.0 Well suited for classroom applications Class E Fiber Longer distance transmission No PoH Up to 100 meters Up to 30 meters Up to kilometers
Basic 2: Consider the Application and Environment Do you have power where you need it? Power over HDBaseT (PoH) is a variation of Power over Ethernet (PoE) Fully capable of safe delivery of 100 Watts over four pairs However, today s application is primarily for powering the transmitter or receiver at typically less than 10 Watts Certified bi-directional PoH transmit and receive extenders can be powered at either the source or display end of the link for superior installation flexibility
Basic 2: Consider the Application and Environment Bi-directional Power-over-HDBaseT Powering the Transmitter from the Receiver End PoH stays within the HDBaseT Link Power Adapter
Basic 2: Consider the Application and Environment Power Adapter Bi-directional Power-over-HDBaseT Powering the Receiver from the Transmitter End PoH stays within the HDBaseT Link
Basic 2: Consider the Application and Environment Transmitter/receiver pairs draw about 10-15 watts half of that is sent to the other end Typically < 300mA @ 48 VDC on the 4 pairs even during startup Be aware of Power over Category cable (PoC) devices that may not comply with PoH or PoE standards and could lead to incompatibility or risk of equipment damage
Basic 2: Consider the Application and Environment PoH is useful for powering auxiliary devices Can displays be powered over the HDBaseT link? HDBT Rx www.hdbaset.org/certification
Basic 2: Consider the Application and Environment Where will the AV link (or links) actually go? Is it a simple point-to-point conference table to projector? How many connection points are really required? Does the link need to run back to the TR? Consider the effect on distance capability, which can be reduced by numerous connections Leviton recommends a maximum of four connectors in the link
Basic 2: Consider the Application and Environment Are displays distributed throughout the facility? Home runs are better than daisy chaining to support powered devices and for future re-purposing of cabling Be aware of the affects of Alien Crosstalk in bundles and adjacent to LAN cabling even over short distances Are you planning to use existing cable infrastructure? Test the existing cabling and connectivity to assure links meet Cat 6A TIA performance standards
Basic 3: Consider the Capability of Twisted-Pair Cable HDBaseT Alliance specification lists Cat 5e, Cat 6 and Cat 6A UTP cabling as supported media types TIA Specifications for standards compliant UTP cable Cat 5e Maximum Frequency = 100 MHz Cat 6 Maximum Frequency = 250 MHz Cat 6A Maximum Frequency = 500 MHz Designed to carry 100-250MHz PAM-5 signals (1000BaseT) Designed to carry 500MHz PAM-16 signals (10GBaseT) 10GBaseT and HDBaseT use PAM-16 signals
Basic 3: Consider the Capability of Twisted-Pair Cable Both Ethernet and HDBaseT use differential mode balanced line signals Twist creates the balanced pair Pair twist pitch and consistency reduce internal crosstalk and radiated emissions Cat 5e 100MHz Cat 6 250MHz Cat 6A 500MHz
Basic 3: Consider the Capability of Twisted-Pair Cable In order to drive a PAM-16 signal over 100m, signal strength and complexity are greatly increased causing Alien Crosstalk (AXT) AXT is coupled to a channel from other cables and connectivity outside and in close proximity AXT cannot be predicted, and therefore cannot be reduced through noise cancellation within active equipment AXT can only be controlled through proper design and installation of passive cable media
