The EX90 is really the big brother to the EX60. In both form and function, it is quite evident that they share a common ancestry. Like the EX60, the EX90 includes an integrated 10/100/1000 switch to facilitate both network and workstation connectivity via a single network drop.
It has a 24-inch HD display capable of 1920x1200 resolution and 5-ms response time, and provides a 160-degree viewing angle. As a video communications endpoint, it supports resolutions of 1080p30 and 720p60.
The tilt of the unit can be adjusted within the range of 5 to 15 degrees from vertical. The accompanying TelePresence Touch 8 pad allows for simple, intuitive operation of the endpoint. In addition to the integrated microphone and dual front speakers, the EX90 also has a built-in subwoofer for higher sound quality.
It also includes a handset for times when private audio communication is desired. The use of an external headset and microphone is also supported via the dual USB ports or 3.5-mm jacks built in to the unit.
The EX90 includes a TelePresence PrecisionHD camera that can be used as a document camera by moving it to point straight down. When it detects that it is being moved into vertical position, it flips the picture so that both parties see the document right-side up. The camera also has a privacy shutter built in to the bezel.
Unlike the EX60, the EX90 has an optical, motorized zoom feature. The camera has a 1/3-inch 2.1-megapixel sensor, allowing a 45- to 65-degree horizontal / 40- to 27-degree vertical field of view, depending on the zoom factor.
Another key difference between the EX60 and EX90 is support for a feature known as multisite. EX60 does not support it, whereas EX90 does. This feature is enabled through the addition of an option key in the TC code. Like the EX60, beginning with CUCM 8.6, the EX90 can be registered as a SIP endpoint. As mentioned, while the endpoint can be used with either VCS or CUCM, future development efforts will be primarily focused on CUCM-related functionality.

Regardless of deployment model, the EX90 supports H.261, H.263, H.263+, and H.264 video standards. As with its counterpart, it can serve as a nicely sized second monitor for a DVI-I or HDMI attached workstation or laptop. Through this connection, content can be shared into the video stream at 1080p. The EX90 also has additional capabilities including HDMI in, HDMI out (dual display option), as well as audio in/audio out (3.5-mm jack on rear panel).
The EX90 is supported with Cisco TelePresence software version TC3.1 and later or TE6.0.
