Note the following important points regarding the previous diagram:
• 16 external inputs are routed into the 16x8 crosspoint matrix.
• PGM, PV, and Clean Feed are fed into the 24x8 crosspoint matrix ,
which then routes the signal to Aux Buses 3 to 10.
• The crosspoint matrices provide 16 outputs:
~ Background
~ Preset
~ Key 1 Video
~ Key 2 Video
~ Key 3 Video/Aux 1
~ Key 1 Alpha
~ Key 2 Alpha
~ Key 3 Alpha/Aux 2
~ 8 x Aux (Aux Buses 3-10)
• Each output, with the exception of the 8 untimed Aux Buses, is routed
through a Deserializer Module (4000A-061) from which the signals
feed the MLE.
• Aux Buses 1 and 2 may be routed through Deserializer Modules,
through blanking circuitry (not shown), re-serialized in Serializer
Modules (4000A-062), and out through BNC connectors.
• The MLE is self-contained, with provisions for several optional
modules: Border Generator (4000A-049), Squeeze & Tease (4000A-
048), Squeeze and Tease 3D (4000A-148), Aspectizer (4000A-050),
and the Ultimatte Insider™. The MLE outputs five signals:

• Frame Processor (CPU) (4216A-001)
The Frame Processor resides in the slot of the chassis. It contains the
main system microprocessor which handles high-level control
functions and all of the remote serial communication for the Synergy 1
frame. It also provides connectors for mounting of all of the optional
daughter boards.

Coming out of the MLE are five outputs:
• Program — routed to a rear-chassis BNC output connector, to the
Preview Matrix, and also back into the crosspoint matrix.
• Preview — routed to a rear-chassis BNC output connector and to the
Preview Matrix.
• Clean Feed — routed to a rear-chassis BNC output connector and also
back into the crosspoint matrix.
• Aux 1 — routed to a rear-chassis BNC output connector through the
video switch. (Synergy 1 only)
• Aux 2 — routed to a rear-chassis BNC output connector through the
video switch. (Synergy 1 only)
Serializer Modules
Program, Preview, Clean Feed, Aux 1, and Aux 2 video each come out of the
MLE as parallel 10-bit data. These signals are then routed through small Serializer
Modules (4000A-062) as shown below.
Serializer Module
Serializer Modules convert the parallel digital video data into the serial format,
which can then be routed via coax cables through your facility, or used internally in
the Synergy’s crosspoint matrix. The crosspoint matrix requires that everything must
be in the serial format. Thus any signal that is routed to the crosspoint matrix must
go through a Serializer Module, from any given output.
Note that Clean Feed has a dedicated BNC output, just like Program and Preview,
but DVE Send is only available to the outside world by routing it into the video
switch, and then out via an Aux Bus. There is no DVE Send BNC output.
Aux Buses
The routing for Synergy 1’s Aux Buses is described in this section. Refer to the
illustrations on the following page.
Aux Buses 1 and 2 can be configured for either “timed” or “untimed” operation.
• For untimed Aux Bus operation, the lower circuit is used — going
directly from the crosspoint matrix to the video switch, and then to the
output BNC connector. No other processing is required.

(timed)
The Deserializer Module converts the signal from serial data to 10-bit
parallel data, but it also handles the timing of the inputs by auto-timing
the signal to reference.
The signal is then routed into the MLE video processing core, through
circuitry that performs blanking insertion, signal clean-up, and
synchronization to system reference. Note that the blanking does not
affect the imbedded ancillary data in the vertical interval.
As the last step, the signal is routed through a Serializer module,
converted from parallel to serial, then through a driver (video switch)
to the output BNC connector.
Aux Buses 3 to 8 inclusive are untimed, and are switched directly on the crosspoint
matrix. Refer to the illustration below:

Regarding timing, there is very little delay on the untimed Aux Bus outputs. The
timed Aux Bus outputs, however, are delayed such that they are timed to match the
PGM output of the switcher.
PLL and SPG
The PLL (Phase Lock Loop) and SPG (Sync Pulse Generator) circuitry takes the
reference video signal from the REF IN BNC (in serial form) and creates a clean
clock — plus various other sync pulses for the system.
Dedicated
REF IN BNC
Within the PLL and SPG circuitry, there are two modes in which the Deserializer
Module (4000A-061) can work:
• The simplest mode is when the Deserializer is used for the reference.
The microprocessor tells the module to add a delay of [n] clocks. The
signal comes in — it is then delayed and fed out.
• On all other buses (e.g., MLE, Aux Buses) system software requests a
delay of [n] clocks from the reference. The reference sends a sync
pulse, then the module looks at incoming video and adjusts the delay
dynamically — delaying video by [n] from the reference signal.

The output of the Deserializer module is routed to the SPG, that in turn generates
Horizontal Sync, Vertical Sync and Field Pulse.
Another output from the Deserializer module is a 27 MHz clock, which is routed to
the PLL (Phase Lock Loop). Within the PLL is a stable oscillator that regenerates
the 27 MHz clock, filtering out all jitter and generating the stable (clean) 27 MHz
signal that clocks the entire system. The net result is that if you have a jittery
reference signal, the switcher’s output will not be adversely affected on its outputs.
The PLL loop bandwidth is 300 Hz. Therefore, low frequency
jitter below 300 Hz will not be filtered out by the PLL.
If the reference is not present (or is lost), the PLL and SPG still continue to run. In
this condition however, the switcher can default to 625-line mode and the clock rate
is not guaranteed. Furthermore, the switcher may lose lock with the video.
System Timing and Non-Sync Detectors
Non-sync detection is based in the Deserializer Module (4000A-061). As discussed
above, a simple delay can be used, or the module can look at the reference signal and
then determine an offset.
The only information that the Deserializer Module has about the reference is
Horizontal Sync. The module itself guarantees that the video will be locked
horizontally — after video passes through it.
Additionally, the module’s vertical sync output is examined, and compared to that of
the reference. If the two signals do not match vertically, the system considers the
video to be non-synchronous — and the N/S (Non-Sync) LED lights on the panel
(on the bus on which the source was chosen). In this non-sync situation, the selected
video may be stable, but it will be shifted vertically.
If you have an input signal that is out of the timing window (too far out of time
horizontally), the signal may lock to the next (or to the previous) Horizontal Sync
pulse. This situation, however, can introduce a one-line offset, either up or down —
and the N/S light will again come on.
2-10 • System Architecture Synergy 1 Maintenance Guide • Synergy 1/Synergy 100 Edition (Iss. 1)
The Synergy 1 switcher “auto-times” around the reference — on the inputs. Synergy
1 specifications allow a ¼ line tolerance with regard to timing. If your input is ¼ line
early or ¼ line late, relative to the reference, the system can time it properly and
make it lock exactly. If the signal is greater than the allowed tolerance, the system
can not guarantee that it will lock to the correct “H.” It may possibly lock to the
previous H, or to the next H.
Please note:
• In order for Synergy 1 to properly auto-time late signals (with respect to the
reference), the switcher’s reference delay must be set to at least the amount of time
that the incoming signal is late. For example, if a video source arrives 1 microsecond
later than the reference, the reference delay must be set to at least 1 microsecond for
Synergy 1 to properly auto-time the source. In Chapter 7 of the Synergy 1
Installation Guide, Synergy 1 Edition, refer to the “Reference Delay Adjustment”
section for details on setting the reference delay. In the Synergy 1 Installation
Guide, Synergy 100 Edition, see the “Outputs Menu” section in Chapter 7.
• Synergy 1 has one non-sync detector per bus (including the Aux
Buses).
• The non-sync detection circuitry itself resides on the Frame Processor
board. However, the detection circuitry uses the V Sync pulse from the
Deserializer Module to determine sync status.
• The N/S LED lights only when a non-synchronous input is selected on
a given bus. Thus if three non-sync sources are chosen on PGM, KEY
and PST, each N/S LED will light on the respective buses.
• There are no non-sync detectors on untimed Aux Buses.

CPU Structure
This section describes the Synergy 1’s CPU structure, in terms of which areas are
controlled by which specific microprocessors. Effectively, Synergy 1’s CPU
structure functions as a master/slave duo-processor system, where the master
processor controls high level functionality, and delegates other tasks to slave
processors.
In a Synergy 1 system, you have two microprocessors in the frame, plus one in the
control panel. Each microprocessor is a 50 MHz floating point DSP (TMS-320-
C32, manufactured by Texas Instruments), and each is identical — running at the
same clock rate.
Processor distribution and functionality is as follows:
• One “Frame Processor” on the Frame Processor Board is responsible
for performing high level functions, and issuing commands to the MLE
processor. This processor manages all serial channels to and from the
chassis, and manages communications with all other peripheral devices
connected to the frame. In addition, it manages communications with
the control panel, and in the case of the Synergy 100 Control Panel,
communicates to the Control Panel Processor which LEDs to turn on
and off and which text to write in the various displays on the panel.
™
The Frame Processor also controls the Ultimatte
Dual Aspectizer
®
board and non-MLE functions, including all Aux
Insider board, the
Bus functions, and all crosspoint switching.
• One “MLE Processor” on the Frame Processor Board processes high-
level information that pertains to the current state and specific
commands issued on the MLE.
This high level information includes which functions are enabled or
disabled, and what configurations have been set up by the user on the
control panel. The MLE Processor translates that information, and sets
the required bits in the hardware to complete the command request.
Following are several examples:
~ If you press WIPE in the MLE and select the circle wipe in the
Pattern Control Group, that information goes to the Frame
Processor — which in turn tells the MLE Processor that a circle
wipe has been requested. The MLE Processor then draws the
proper tables required to make the image.
~ If you pull the Fader from Program to Preset, the Frame Processor
receives that information and analyses how it affects the high level
structures within the switcher — e.g., which buses are moving,
what type of effect has been requested (Dissolve, Wipe, DVE,
etc.). The Frame Processor then passes the current state of a
particular field to the MLE Processor, which then writes the
effect’s specific values to the video processing circuitry.
~ If you press the AUTO TRANS button, that command goes from
the control panel to the Frame Processor, which in turn keeps track
of which state the transition is in. Commands are then issued to the
MLE Processor to perform the transition at (for example) 4% in
one field, 8% in the next field — until complete. The MLE
Processor in turn does not process the video itself, but rather issues
