This is a second generation of our JKGEN - special signal generator for digital audio.
The main goal was to add more features and possibilities, without significant increasing the price. That is why we do not make the expensive custom metal case, as in the 1st version. We use one of the standard plastic case, which is much cheaper.
We are also decide to put the maximum features in the hardware, even if not all of them will be used now. Because of a very easy firmware upgrade procedure, this can be done later.
Target application: DAC and other digital and analogue audio system production tests, research, development, debug and repair.
Low Frequency Digital Audio Signal Generator
New in the 2nd generation:
more information on the screen because of a bigger display size
better GUI with easy to understand pictograms
more controls (4 push buttons plus encoder) to speed up operation
better analogue output for PCM (I2S only) and DSD
extended sample rate
wide voltage range of the output digital signals (from 1.8V to 5V) to easy connection with various equipment
variable SPDIF coaxial output voltage
added TMD128 and TDM256 signals
master and slave MCLK with extended frequency range
master and slave I2S bus operation *
added PWM CMOS-level output generator
added wide band noise generator *
added Multy Tone signals (6 types)
added some control signals, like PCM/DSD and Mute
I2S bus have 4 data lines for more convenient operation with multichannel DACs
wide input power voltage range operation
remote control from PC for the test automation
* - in the later firmware versions.
