INTRODUCTION
Yosemite Family Overview
Introduction
The Yosemite Family of large-sized matrix routing switchers provides exceptional performance in
compact frame designs ideal for Broadcast, CATV, Industrial, and Government applications.
Ranging from 64x64 to 128x128 Inputs / Outputs, frames can be expanded from 32x32 up to
128x256 and are able to house both analog and digital video modules in the same frame.
Optional redundant power supplies and control processors are available with the standard frontloading and hot-swappable I/O modules. Yosemite
systems switch multiple analog and digital signal formats,
including AES/EBU synchronous or asynchronous audio,
serial digital video (SDI), monaural or stereo audio,
analog composite video, analog component video, time
code, and machine control. Sierra video’ building-block
module design; based on frame size, different crosspoint
modules, and input / output modules; was specially
applied to the Yosemite Family, providing an array of
configurations.
The Yosemite Family Control System is based our
innovative and time-tested Tahoe Control System,
incorporating many powerful features and numerous
options. The Yosemite three-port controller can be directly interfaced with a wide variety of 12-key
and alphanumeric control panels, as well as supported by third-party control systems.

Video Overview
Analog Video Signal Path Overview
The Yosemite Family of analog video routing switchers are based on conventional “single stage”
crosspoint matrix design. The signal path consists of three elements or modules:
1. Input buffer
2. Crosspoint modules
3. Input / output sub-assemblies
17
SIERRA VIDEO
Input Buffers
Each input buffer consists of a small adapter on the rear of the frame that converts the 75 ohm analog
video input into a buffered, very low impedance load (under 5 ohms). Each adapter module contains a
400 Mhz linear circuit. The signal is distributed via a PWA (“Printed Wiring Assembly,” also known as a
circuit board) motherboard to the crosspoint matrix portion of the router.
The 64x64-frame assembly consists of two sections. Each of these sections has 32 input buffer
assemblies and a motherboard which distributes the video signals. The 96x96 routing switcher consists of
three sections of 32 inputs each; the 128x128 frame consists of four sections of 32 inputs each. All
analog Yosemite Family video routing switchers – including wide bandwidth systems – use the same
input buffer adapter.
The obvious advantage to having each individual input buffer mounted externally is easy maintenance.
Changing an individual input buffer does not require powering the system down, nor does it require
unsafe internal repairs. Please consult SVS Customer Service before moving any of the input buffers.
Oftentimes Yosemite routing switchers are ordered with future expansion in mind. For example, a
128x128 frame can be ordered and configured with only 64 inputs and 64 outputs, requiring only 2 of the
aforementioned input buffer assemblies and motherboards. In these cases, the input buffers will be wired
for the customized configuration, possibly changing the input number as indicated on the frame. Do not
move any of the input buffers installed by the factory without contacting SVS Customer Service. This
may disrupt system performance if wired incorrectly.

VIDEO OVERVIEW
Crosspoint Modules
The Yosemite Family analog video switcher uses the newest technology available for the crosspoint
matrix. The crosspoint matrix is built using 250MHz high performance surface mount crosspoint arrays.
The crosspoint modules in the Yosemite analog video routers are 32x32 switching sub-matrices. The
32x32 matrix consists of eight 16x8 250MHz crosspoint IC’s. Likewise, to offer ultimate flexibility in the
Yosemite line, the 96x96 analog video routing switcher uses only 6 of the crosspoint IC’s to make a
32x24 switching sub-matrix. This results in very exceptional performance and high system density
throughout the Yosemite series.
19
SIERRA VIDEO
Input / Output Sub-assemblies
Yosemite 6464V/D
The 32x32/ 32x24 crosspoint modules are part of a larger plug-in sub-assembly. In the 64x64 system, two
32x32 crosspoint modules are combined with a 32-channel output assembly to constitute a 64x32 subunit.
A complete 64x64 7RU system consists of two of these sub-assemblies. A 32x64 system would consist of
32 input buffers installed with only one of the two possible 32x32 crosspoint modules installed in each
64x32 assembly. The result would function as a 32x32 sub-assembly.
Yosemite 9696V
The 96x96 11RU frame has positions for four 96x24 matrix sub-assemblies. Each of these is built from up
to three 32x24 crosspoint sub-assemblies. In this situation, eight of the outputs on each 32x32 module
are not used.
Yosemite 128128V/D
The 128x128 14RU frame has positions for four 128x32 matrix sub-assemblies. Each of these is built
from up to four 32x32 crosspoint sub-assemblies.
Interchangeable Assemblies
Except for the output driver half of the output assembly and the power supply(ies), the other modules are
interchangeable between 64x64, 96x96, and 128x128 systems. This includes the control processor
module.
20
VIDEO OVERVIEW
Digital Video Signal Path Overview
The Yosemite Family of digital video routing switchers are based on the same aforementioned
conventional “single stage” crosspoint matrix design. The signal path consists of four elements or
modules:
1. Input buffer
2. Crosspoint modules
3. Input / output sub-assemblies
Input Buffer
The input module assembly for each input of a Yosemite digital video router contains an automatic
adaptive cable equalizer and four differential, controlled-impedance, transmission line drivers. Each input
buffer consists of a small adapter module on the rear of the frame that is a combination 15 through 600
Mbps adaptive cable equalizer and fan-out distribution amplifier. The adapter accepts SDI data rates and
connects to the internal crosspoint sub-assemblies directly.
The 64x64-frame assembly consists of two sections. Each of these sections has 32 input buffer
assemblies and a motherboard which distributes the video signals. The 128x128 frame consists of four
sections of 32 inputs each. All digital Yosemite Family video routing switchers use the same input buffer
module.
The obvious advantage to having each individual input buffer mounted externally is for easy maintenance.
Changing an individual input buffer does not require powering the system down, nor does it require
unsafe internal repairs. Please consult SVS Customer Service before moving any of the input buffers.
Oftentimes Yosemite routing switchers are ordered with future expansion in mind. For example, a
128x128 frame can be ordered and configured with only 64 inputs and 64 outputs, requiring only 64 of the
aforementioned input buffer assemblies and two motherboards. In these cases, the input buffers will be
wired for the customized configuration, possibly changing the input number as indicated on the frame. Do
not move any of the input buffers installed by the factory without contacting SVS Customer Service.
This may disrupt system performance if wired incorrectly.
Crosspoint modules
The motherboard design used in Yosemite video routing switchers incorporates a number of unique
design features. In the digital router, the motherboard provides a separate, very high-speed differential
transmission line to each crosspoint module in the system. This avoids any need for additional internal
distribution devices and allows all crosspoint IC’s in the system to be end-of-line terminations. This means
that there will be no high impedance internal stub connections that may cause reflections that often
equates to jitter problems.
21
SIERRA VIDEO
As with the Yosemite analog routing switcher, we have based our digital video design on the most up-todate crosspoint technology. The basic switching device is a GaAs (Gallium Arnside) 64x33 1.5Gbps
integrated circuit.
22
VIDEO OVERVIEW
Input / Output sub-assemblies
The 64x64 digital video router is comprised of two plug-in sub-assemblies. One half of each of these
assemblies is a 64x33-crosspoint module. The 64x33 crosspoint module mates with a 33 channel output
driver module to complete the sub-assembly.
Because the basic crosspoint unit is a 64x33 module, the 96x96 frame is not suitable or cost-effective for
digital video.
The 128x128 frame has up to four plug-in sub-assemblies. Each of these is comprised of two 64x33
crosspoint modules and a 33 channel output driver. The output driver has thirty-three 2x1 switchers that
select between the output of the two 64x33 crosspoint modules. Thirty-two of these 2x1s are comprised
of ¼ of an 8x8 crosspoint IC configured as a 2x1 switch. Consequently, the 128x128 digital router signal
path only passes through two cascaded crosspoints.
The outputs of the 2x1 switches connect to a re-clocking circuit. The re-clocking circuit automatically
switches to the correct data rate, which supports up to four data rates. The standard digital Yosemite
64x64 and 128x128 systems are shipped with re-clocking set to 143mbps, 177mbps, 270mbps, and
360mpbs. If another data rate is desired or if the re-clocker needs to be bypassed, contact Sierra video
for additional information.
23
SIERRA VIDEO
Additional Monitoring Outputs
As stated in the above paragraphs, the “33rd” output on each sub-assembly is an additional output. The
Yosemite 64x64 system is actually a 64x66 and the 128x128 is actually a 128x132. Each of the “33
outputs appears on the BNC connectors on the front of the output module assembly, rather than on the
rear of the frame.
The most common use of the 33
are mapped to outputs 65 and 66. These extra outputs must be addressed on the control processor to
function properly. For more 64x64 information and for 128x128 system functionality, please consult Sierra

”
Analog to Digital Upgrade Capability
A key feature of Yosemite Family Routing Switchers allows the same frame to be used for analog or
digital video routing.
An analog router can be changed to a digital system by replacing the analog modules with digital
modules. Because digital video requires more power, upgrading power supplies is also required. This
permits a system to be upgraded in the field from an analog system to a digital system.
Video / Audio Compatibility
All of the Yosemite video frames mentioned above are compatible with both Yosemite audio frames and
modules. Moreover, Yosemite can be interconnected to most other Sierra Video units, or RS-422 Port
routing switcher. For more information, on combining systems to include analog, digital, mono audio,
stereo audio, or any other format, please contact Sierra video.
