Single Converter SC

 

Features common to SCRF and SCM converters:


• Compact, low power, surface mount design

• Front panel tri-color Status LED

• Up to 16 user programmable options

  1. Extremely stable output: +/- 3% levels

• 10 bit video D/A for greater than 54dB dynamic range

• EEPROM memory for FPGA firmware, field upgradeable

• Automatic Sleep Mode for low power standby operation


Features unique to SCRF converters:


• Flexible built-in RF Modulator:

    - Up to 15 selectable carrier frequencies

    - Programmable between 28.5-880MHz (actual channels vary by model)

    - Supports positive/negative video and AM/FM audio modulation schemes

  1. Converter bypass mode for use as stand alone RF Modulator

• Externally adjustable RF channel and audio modulation depth control

  1. 100K gate equivalent FieldProgrammableGateArray (250K on SCRF405A-NTSC)

  2. 8Mb/16Mb FLASH Memory for firmware, settings and default image storage

• Output clock line locked to input clock for perfect conversions

• FLASH Image Memory for storing up to two custom images*

• Unique partial-field memory for stable output syncs

• Extremely accurate algorithms used for conversions:

    - Three line interpolation on all standards (Electronic converters)

    - All internal calculations done to a minimum 12 bit precision

• Versatile I/O:

    - Composite Video Input (NTSC/PAL, 1Vpp, 75 ohm)

    - Composite Video Output (various standards depending on model, 1Vpp, 75 ohm)

    - Stereo Audio Inputs (-10dBV nominal, 0.2Vpp-5Vpp, 20k ohm)

    - RF Output (76dBµV, 75 ohm, approx. 6mV)

    - DC power (7-14Vdc, 250ma)


Features unique to SCM converters:


  1. Supports all the following mechanical standards: 24/20p, 30/12.5p Baird, 30/12.5 TeKaDe, 30/16.6p,

    32/12.5p NBTV, 39/12.5p, 45/15_3i Western, 48/15p, 48/20p, 48/25p, 50/25p, 60/12.5p Baird,

    60/20p, 60/25p

  1. Reference Input allows converter to synchronize with an external AC Mains signal (50Hz or 60Hz) or a Frame reference (12.5Hz to 25Hz) with +/-4% error.

  2. 250K gate equivalent FieldProgrammableGateArray

  3. 8Mb FLASH Memory for firmware, settings and default image storage

• Three full frame memories.

• Extremely accurate algorithms used for conversions:

    - All internal calculations done to a minimum 12 bit precision

• FLASH Image Memory for storing a custom image

• Versatile I/O:

    - Composite Video Input (NTSC/PAL, 1Vpp, 75 ohm)

    - Video Output (various standards, 1Vpp, 75 ohm)

    - Reference Input (+/-30V, 20k ohm, Zero crossing, programmable edge)

    - DC power (7-14Vdc, 200ma)




  1. *All monochrome SCRF models and SCRF405A-NTSC have FLASH Memory for two default images
