An Ultra-stable Video Sync/Master Clock from TASCAM

The TASCAM CG-1800 video sync/master clock generator gives you an ultra-stable clock signal, thanks to its high-precision oven-controlled crystal oscillator. On top of that, the CG-1800's jitter management and glitch-free relocking circuits save your digital system from destructive noise and dropouts. Providing you with a plethora of word clock, video, and digital outputs, the CG-1800 is as useful for large-scale digital multimedia systems as it is for smaller audio/video studios. At Sweetwater, we're all about high-end, cutting-edge technology like the TASCAM CG-1800 video sync/master clock generator. If your rack of digital gear is suffering from the jitters, you need the TASCAM CG-1800 video sync/master clock generator to put it in its place!

TASCAM CG-1800 Video Sync/Master Clock Generator at a Glance:
  • Oven-controlled crystal oscillator provides ultra-stable clock signal
  • Jitter management circuit improves sonic performance
  • A plethora of outputs to tackle systems of all shapes and sizes
  • Built-in functions for troubleshooting and maintaining top performance
Oven-controlled crystal oscillator provides ultra-stable clock signal

The TASCAM CG-1800 video sync/master clock generator utilizes a high-precision OCXO (oven-controlled crystal oscillator) to provide you with an ultra-stable clock signal for your digital audio/video system. Because it is not influenced by the temperature of the environment, the CG-1800's OCXO is able to generate a clock frequency precision of an unprecedented 0.01ppm and a word output frequency stability of +/-0.005ppm or less per day. Lesser clocks utilize a TCXO (temperature-compensated crystal oscillator), which doesn't account for temperature at all, resulting in highly-frustrating synchronization errors.

Jitter management circuit improves sonic performance

TASCAM's original jitter management circuit incorporates a high-performance video clock generator engineered with a FPGA (field programmable gate array) and PLL (phase-locked loop) circuit with a discrete filter. The result is that an ultra-stable clock signal is provided to the CG-1800 master clock generator's video and word clock outputs, providing you with an exceptionally stable system. Also, the CG-1800's glitch-free relocking circuit prevents the noise, dropouts, and skipping sounds that often plague inferior clocks.

A plethora of outputs to tackle systems of all shapes and sizes

Not only does the TASCAM CG-1800 video sync/master clock generator give you 12 word clock outputs and 4 video outputs, you also get 2 AES3/AES11 and 2 S/PDIF outputs, making the CG-1800 as useful for large-scale digital systems as it is for smaller audio/video studios. On top of that, 2 of the CG-1800's word clock outputs also support x2Fs, x4Fs, and 256Fs output, making it easy for you to integrate the CG-1800 with Pro Tools and other DAW software.

Built-in functions for troubleshooting and maintaining top performance

In order to keep your digital system in tip-top shape, the TASCAM CG-1800 video sync/master clock generator gives you multiple functions to support maintenance and to help you identify any issues if problems occur. Because crystal oscillators change over time, regular calibration is necessary to avoid sync issues. The CG-1800's self-correction function lets you conduct maintenance using an external signal input and simple operations. The CG-1800 also has an analyzer function that measures output device termination, input level, and input frequencies to help you troubleshoot any issues that you might encounter.

TASCAM CG-1800 Video Sync/Master Clock Generator Features:
  • OCXO (oven-controlled crystal oscillator) provides ultra-stable clock signal
  • Jitter management circuit prevents noise, dropouts, and skipping
  • A plethora of outputs to tackle systems of all shapes and sizes
  • Built-in functions for troubleshooting and maintaining top performance
  • A single circuit board is used for each connector to suppress interference between connectors
  • Amphenol BNC connectors use nuts for coupling to provide extra durability
Whip your digital audio/video system into shape with the TASCAM CG-1800 video sync/master clock generator!

What Does "Special Order" Mean?

A special-order product is one that we don't normally keep in stock. We order it from the manufacturer as soon as you order from us. We have great relationships with all the manufacturers we carry, so we can get your special order to you as fast as or faster than anyone else. Remember that special orders are non-returnable and non-cancelable, so make sure the item is right for you. A Sweetwater Sales Engineer can help you decide — call (800) 222-4700 for assistance!
