SYNNER-E MOTHERBOARD

MECHANICAL
Standard Crystal Vision module 266mm x 100mm
Weight: 210g without piggyback; 250g with piggyback fitted
Power consumption: 11 Watts

VIDEO INPUT
SDI 270Mbit to EBU 3267-E and SMPTE 259M
Cable equalisation >200m Belden 8281 or equivalent
Auto 625/525 line selection
The board can accept up to two groups of embedded audio. One of these groups of embedded audio can contain one or two channels of Dolby E

SDI OUTPUTS
SDI 270Mbit to EBU 3267-E and SMPTE 259M with inserted EDH
Maximum of four SDI outputs (two outputs with frame rear module RM04, RM07 and RM30 and four with RM26)
<500ps 1kHz jitter and <800ps broadband jitter from stable 300mV Black and Burst reference
<500ps 1kHz jitter in delay mode (low frequency jitter follows SDI input in delay mode only)
Active reclocked SDI loop-through available on RM07 and RM26 rear modules - loop needs SYNNER-E to be fitted
The board can embed up to two groups of audio data. Remaining non-conflicting groups in the HANC space can be bypassed through the HANC cleaner
All external audio inputs are linear audio only. They are subject to the same tracking delay process as the de-embedded group audio

ANALOGUE VIDEO OUTPUTS
Maximum of two PAL/NTSC composite outputs. One output with frame rear module RM30 and two with RM07 and RM26. (NB. No composite outputs with RM04)
Frequency response: +/-0.3dB 0 to 5MHz
Noise: <-54dB weighted luminance or chrominance

ANALOGUE REFERENCE
Analogue Black and Burst, mixed syncs or video
Amplitude of syncs 150mV to 4V
Optimum jitter performance is from analogue Black and Burst plus 300mV syncs to EBU N14-1988
Reference rear module loop-through available on RM26 and RM30 - loop does not need SYNNER-E to be fitted as rear module has passive circuitry required
Reference active loop-through available on RM07 - loop needs SYNNER-E to be fitted

VIDEO TIMING ADJUSTMENTS
In synchroniser mode the timing of the output (with respect to the reference in) may be adjusted by any number of lines up to a whole video frame. Horizontal timing adjustment is also possible in 37nS steps
In delay mode the reference is not used and the delay through for the SDI is set by the same timing adjustments

DELAY THROUGH BOARD
3.8us min - 2 fields max

FREEZE FUNCTIONS
Automatic freeze is available when input fails through loss of signal. Can show last good field before picture failure, whole frame in which failure happened or black or blue screen. Can also freeze picture for one second and then go to black or blue
Manual freeze allows SYNNER-E to be used as a simple still store. Selecting single field output can counteract any flicker caused by the interlacing of two fields. Either field can be selected

HANC CLEAN UP
SYNNER-E can make best use of the available HANC data space by removing "marked for deletion" audio groups and repacking the useful audio data

AUDIO INPUTS (OPTIONAL)
One piggyback can be added to the main board to enable either input of 2 x AES or 2 x analogue stereo pairs
Use HD-AIP2, HD-DIP2 or HD-DIP2-RS piggybacks to input analogue, synchronous AES or asynchronous AES audio

AUDIO TIMING ADJUSTMENTS
The audio is normally delayed by the same amount as the video but an additional delay can be added to the audio of up to 20ms
Tracking delay auto or off

AUDIO REPLACE
Embedder can replace audio stereo pairs already present on SDI input with audio from the input piggyback

EMBEDDER TIMING PERFORMANCE
Interchannel: <1 clock cycle
Audio to video: Min 320us for AES audio input. Min 1ms for analogue audio input
De-embedder automatically handles asynchronous and synchronous audio

AUDIO MONITORING
One miniature front mounted audio jack and switch selects individual stereo audio analogue monitoring on both embedder and de-embedder
Please note that you cannot hear valid audio on the Dolby E channel

EDH
EDH insertion on output

AUDIO FOLLOW OUTPUT
TTL output is provided on the same D-Type as GPIs to indicate the video delay through the synchroniser. The length of the pulse is equal to the length of the video delay

LED INDICATION OF:
SDI input present
Analogue reference present
Power supplies okay
Delay less than 24 lines
Store frozen
Selected audio group missing from input

GPI INPUT LEVELS
Electrically: Will tolerate 0V to 30V, pulled up to +5V through 10 kohm

GPI OUTPUT LEVELS
Electrically: Open collector transistors 30V, 330 ohm current limit resistors. Pulled up to +5V through 10 kohm

GPI INPUTS
Recall presets 1 to 16

GPI OUTPUTS

LOCAL CONTROL
Board edge with 10 character alphanumeric display

REMOTE CONTROL
RS422/485

Statesman allows control from any PC on a network
SNMP monitoring and control available as a frame option
NB. SYNNER-E does not have front panel control

HD-AIP2 DUAL ANALOGUE AUDIO INPUT PIGGYBACK

AUDIO INPUT
Two analogue stereo pairs or four mono channels. 24 bit quantising A to Ds. High input impedance (20 kohm) balanced

INPUT LEVEL RANGE
0dBFS = +28dBu max / 0dBFS = +12dBu min
Factory set default: 0dBFS = +18dBu or +24dBu by on board link

HD-DIP2 AND HD-DIP2-RS DUAL DIGITAL AUDIO INPUT PIGGYBACKS

AUDIO INPUT
Two 20 bit stereo pairs. AES3 110 ohm or HiZ (balanced) D-Type, or AES3-id (unbalanced) 75 ohm BNC. Set by on board jumper links
