MECHANICAL
Standard Crystal Vision module 266mm x 100mm
Weight: 200g
Power consumption: 6.5 Watts

ANALOGUE INPUT
Composite, Y/C, YUV or RGB component video input, 1 volt with syncs (Composite input only with RM24 frame rear module)
PAL and NTSC Y/C
Switchable Betacam levels on YUV input
Can accept RGB input with integral sync pulses on all three components, on green only or no syncs. Should the video not have syncs present, an RGB external syncs input is available on the RM01, RM25 and RM27 rear modules
625 line PAL or 525 line NTSC

ANALOGUE REFERENCE
Analogue Black and Burst, mixed syncs or video reference
Amplitude of syncs 150mV to 4V
Link on PCB selects 75 ohm termination or high impedance for loop-through

VIDEO OUTPUTS
SDI 270Mbit to EBU 3267-E and SMPTE 259M with inserted EDH
Maximum of four SDI outputs depending on the input format and the rear module fitted:
Single height RM01 gives four outputs with composite input, three outputs with Y/C input, two outputs with YUV input or RGB input with integral syncs, and one output if RGB input with external syncs
Single height RM23 gives three outputs with composite input, two outputs with Y/C input and one output with YUV input or RGB input with integral syncs
Single height RM24 gives two outputs (composite input only)
Quad height RM25 gives four outputs with composite or Y/C input, three outputs with YUV input or RGB input with integral syncs and two outputs if RGB output with external syncs
Double height RM27 gives four outputs with composite or Y/C input and three outputs with YUV input or RGB input (with or without integral syncs)
Black and Burst rear module loop-through available when using RM23, RM24, RM25 and RM27 - loop does not need ADDEC to be fitted as rear module has all circuitry required
Composite rear module loop-through available when using RM24; composite or Y or G rear module loop-through available when using RM25 or RM27 - loop does not need ADDEC to be fitted
<500ps 1kHz jitter and <800ps broadband jitter from stable 300mV Black and Burst reference

AUDIO FOLLOW OUTPUT
TTL output (0.7V to 5V). On BNC (RM27 only) or available from the D-Type on rear of frame. Pulse length shows delay through store (0 to 40mS)

ANALOGUE PERFORMANCE
12 bit precision 54Mbit (four times oversampling)
Exceptional performance is achieved by a 12 bit five line adaptive comb decoder
Frequency response: +/- 0.5dB to 5.5MHz
Differential phase and gain <1.5 degrees, <1.5%
Signal to Noise: > 60dB
Blanking: To analogue PAL/NTSC specifications, with selectable VBI blanking PAL lines 7 to 22 and 319 to 335. NTSC lines 10 to 20 and 273 to 282

VIDEO TIMING ADJUSTMENTS
With a video timing reference 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
With no video timing reference the delay from input to output is set by the same timing adjustments

DELAY THROUGH BOARD
3 lines min – 2 fields + 3 lines max

FREEZE FUNCTIONS
Manual freeze allows the ADDEC 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

VIDEO GAIN AND LEVEL ADJUSTMENTS
Luma gain
Chroma gain
U gain
V gain
Black level
Chroma phase (NTSC hue)
Adjustable either locally or remotely

Board edge/remote control

ADDEC-310 uses a shaft encoder to access menus for a number of functions using the aid of a ten character alphanumeric display. These include adjustment of video gains and levels

REMOTE CONTROL
Control from frame active front panel and remote panel
Statesman allows control from any PC on a network. Four Statesman menu tabs available: Video properties, Presets, Gains and Factory Reset
SNMP monitoring and control available as a frame option
