MECHANICAL:
All modules are 100mm x 266mm with DIN 41612 connector. (User adjustments and indication at end of board to allow access from hinged front panel.) Weight: 200g. Current required at 5V: 0.8amps

VIDEO SDI INPUT:
SDI 270Mbit to EBU 3267-E & SMPTE 259M. Cable equalisation >200m Belden 8281 or equivalent. Auto 525/625 line selection. May contain embedded audio when input and output frequencies are locked

OUTPUT:
4 outputs SDI 270Mbit to EBU 3267-E & SMPTE 259M with EDH (on some frames and rear panel combinations only 2 outputs available). <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)

ANALOGUE REFERENCE:
Analogue Black and Burst, mixed syncs or video. Amplitude of syncs 150mV to 4V. Link on PCB selects 75ohm termination or high impedance with loop-through (via PCB)

FREEZE FUNCTIONS:
Manual freeze allows the SYN102 to be used as a simple still store. Selecting single field output can counteract any flicker caused by the interlacing of the two fields on a picture with significant movement. Either field can be selected. The single field is output only when the picture is frozen. Automatic freeze is available when input fails through loss of signal. The user can specify to show the last good field repeated before picture failure, the whole frame in which failure happened (useful for diagnostic purposes) or a black screen

AUDIO FOLLOW OUTPUT:
TTL output. Pulse length shows delay through store. Can provide control signal for audio delay systems

GPI INPUT LEVELS:
Active: connect to ground. Inactive: high impedance, or 3 to 48 volts. Input current <50uA

GPI OUTPUTS LEVELS: CMOS levels. Max current 2mA
GPI INPUTS: Freeze
GPI OUTPUTS: Large delay in synchroniser (>25 lines)

LED INDICATION OF:
Power supplies on board. SDI input present. Analogue reference present (vertical syncs detected). Input EDH errors. Large delay in synchroniser (>25 lines). Manual freeze

LOCAL CONTROL:
Variables and options set by shaft encoder with values and prompts on 10 character alphanumeric display on board edge. Output timing adjustment of 0 to 2 fields, set as vertical and horizontal offset
