INTRODUCTION
NVISION manufactures the 6000 and 8000 Series ENVOY Universal Digital Routers.
Each router, identified below, combines compact frame size (with optional redundant
power supplies) and the capability of managing a wide range of signal formats.
• NV6064 provides up to 64 x 64 Inputs and Outputs with dual outputs.
• NV6128 provides up to 128 x 128 Inputs and Outputs with dual outputs.
• NV6256 provides up to 256 Inputs and 128 Outputs with dual outputs.
• NV8256 provides up to 256 x 256 Inputs and Outputs with single outputs.
Designed around a novel high speed crosspoint architecture, each router can handle
data rates from 3 Megabits per second to more than 1.5 Gigabits per second. We call
this capability “Super Wideband” (SWB). The crosspoint structure is combined with SDI
or SWB input/output modules to accommodate SDI and/or SWB data rates within the
same frame, at the same time.
With unique equalizers, reclockers, and cable drivers, the router passes pathological
signals at both SDI and HD-SDI data rates. No signal inversion of the primary outputs
takes place, which is essential for systems handling DVB-ASI data streams since DVB-
ASI is 8B/10B coded and cannot be inverted. Secondary outputs are inverted.
Input and output modules are available for SDI (143, 177, 270, and 360 Mbits) and
Super Wideband (3 Mbits/sec to 1.5 Gbits) data rates. Dual output connectors for each
destination minimize DA requirements on 6000 Series routers.
Expandable in increments of 8 Inputs or Outputs (and 16 Inputs or Outputs on the
8256), combined with the ability to control a router from an existing control system, the
router provides the user with tremendous flexibility. The modules load through the front
and can be “hot swapped” (no need to power down the frame).

routers.
