The TASCAM CG-1800 Video Sync Master Clock Generatorfrom TASCAM CG-1800 Video Sync Master Clock Generatoris specifically designed for small to large-scale video/audio synchronization systems. An OCXO (oven-controlled crystal oscillator) is used for its high precision and because it's not affected by the temperature of the environment. With a clock frequency precision of 0.01 ppm the unit delivers high-precision synchronization with a frequency stability of +/-0.005 ppm or less per day.

External clock jitter is reduced using an original circuit design that incorporates a high-performance video clock generator engineered with a FPGA and a PLL (phase-locked loop) circuit with a discrete filter. This enables a stable clock signal to be provided to the video/word outputs, improving system stability.

In addition to twelve Wordclock outputs and four video outputs, the digital outputs include two AES3/AES11 and two S/PDIF outputs, making this unit useful for large-scale audio/video synchronization systems and a wide variety of other applications. Of the twelve Wordclock outputs, two also support x2 Fs, x4 Fs and 256 Fs output, enabling them to be used in systems with Pro Tools and other DAW software.

The unit features multiple functions to support maintenance and the identification of issues if problems occur, allowing the device to provide troubleshooting support. Additionally, a logging function enables issues to be listed, and saved to a CSV file format on a USB flash drive. A self-correction function allows users to conduct maintenance using an external signal input and simple operations.

Amphenol BNC connectors on the chassis use nuts for coupling for extra durability, along with a single circuit board used for each connector. This provides good resistance to the twisting and pulling of cables, and the suppression of interference between connectors.

• Internal clock uses a high-precision OCXO (oven-controlled crystal oscillator) that is not influenced by the temperature of the environment

• External input connector that supports 10 MHz, allowing creation of systems with even higher precision

• Glitch-free relocking circuit prevents noise and skipping during clock dropouts and recovery

• Numerous output connectors, including twelve Wordclock outputs, enabling the use in large-scale audio synchronization systems

• Supports input and output of a variety of video signal formats, including NTSC, PAL and HD Tri-level

• AES3 and AES11 signals can also be used for external master clock input sources

• Analyzer function that can measure output device termination

• Optimal levels can be provided to other devices by adjusting Wordclock output levels

• Self-calibration function using an external oscillator (Atomic/GPS 10MHz, GPS PPS) (requires a separate PPS-output 10 MHz oscillator with a built-in GPS antenna)

• Wordclock performance up to 192 kHz

• 0.1% pull-up/down for 24F (Film) and 29.97F (NTSC), and 4% pull-up/down for 24F (Film) and 25F (PAL)

• Up to four system settings can be saved to buttons for recall, and saved settings can be imported and exported via USB

• Durable Amphenol manufactured nut-coupling BNC connectors

• Independent circuit boards for each connector prevents contact failures due to twisting

• Panel-lock switch can be used to prevent inadvertent changes to unit operation

• 128 x 64-pixel organic EL display with a wide viewing angle

• Firmware updates possible using the USB port

• 1U rackmount

• RoHS-compliant

Related Questions and Answers

Q: 1. Is there a rack mount bracket for this?

A: Yes! Connectronics 1U Rackmount for Blackmagic Mini Converters - Works Great! Holds 4 Converters.

Q: 2. Is there detailed instructions on how to set this up, I plan on building a stereo rig with two micro cinema cameras but have never hooked up genlock before? By looking at the back of the unit, I'm just confused.

A: Please see pages 76-78 of the Blackmagic Converters Manual for information. You can find all of the product manuals on the Support page of the Blackmagic Design website.

Q: 3. How to set the Generator to 1080i60 tri level in this case? I can't find the setting in the manual. There is 1080i 50. No 1080i60 tri level.

A: Page 86 in the manual shows the settings for 1080i60.

Q: 4. Do I need to download software for using Sync Generator for Synchronize 4 pieces of Hyperdesk Studio 12G Recorder?

A: No.

Q: 5. Can I use BNC splitters (BNC Male Connector to BNC Double Female (T-Shape) Adaptors, for CCTV) (https://www.amazon.com/Splitter-Connector-Double-T-Shape-Adaptor/dp/B06XHT9QHG) at each Ref-Out connector to double the Ref-Out sync-ability to 12 instead of 6?

A: That is not a proper solution and there is no guarantee that it will work. There are analog video distribution amplifiers available on this site that will work for this purpose.

Q: 6. Can this Sync Generator support connect with 4 pieces of "Hyperdesk Studio 12G" (2160P / 60 frame) ? How to set the video format ? Just set to PAL or NTSC ?

A: Yes. You can set the Sync Generator to 1080i60 tri level in this case.

Q: 7. What is the right cable for RED?

A: The following B&H code will be the correct cable: RE7900643

Q: 8. what do you use to control. it does it come with software.?

A: Time code is jammed and synced in this display.

Q: 9. Can you convert a 1080p SDI source to 720P by only clicking the buttons or do you need to do anything else with the software? THanks.

A: The following unit does not support video scaling , it only supports different signals in different formats.

Q: 10. Is there a D-Tap power cable for this?

A: There are several D-Tap to 12V barrel cables on this site.
