Dr. JKILL
Yes, yes - I know that R.L. Stevenson wrote this name as "Dr. JEKYLE", but....
This is Dr. JKILL, that means "Jitter Killer".
100% jitter elimination from your SPDIF/TOSLINK audio source.
Connect JKill to Your DAC with I2S Input and system clock, and the jitter will depend only of how your clock is good!
So, with JKill - we will cook the signal for you, all other sound quality aspects are in Your hands: use good DAC, use good clock, use good amplifier, use good loudspeakers, ohh - and don't forget to prepare you Listening Room!
Including Wife Approval Factor (WAF), of course :)

What is the Jitter and why it should be elliminated? Read the article.
FIFO based device is intended to use with CD/DVD/Media-players, equipped with coaxial SPDIF or optical TOSLINK outputs, providing bitperfect signal, without any influence, any rework or upgrade of these devices.
You need just a high quality double frequency clock generator (512*Fs or 1024*Fs).
Main features:
2 SPDIF inputs
2 TOSLINK inputs
Utilise DIX9211 - one of the "Best In Class" SPDIF receiver
1 I2S input ready (will be implemented soon)
Optional 1 SPDIF and 1 TOSLNK outputs
512*Fs and 1024*Fs External Clocks (optionally - 256 and 384 Fs)
44.1/48/88.2/96/176.4/192 Sample Rate operation
DSD-64 Output from SPDIF DoP signal (optional)
ADC Channel for analogue input (will be implemented soon)
Power Amplifier and/or DAC On/OFF Control
Volume Control (step attenuator) of 3 types
DAC Digital Filter control
1.8" TFT Display or 5 LEDs indication
Encoder or 3 push buttons control
IR Remote control - use YOUR Remote Control Unit (should operate in one of the 5, widely used standards)
Firmware upgrade form USB Disc-On-Key
7.5V, 250mA (less then 2W) power consumption
You can use Front panel with:
TFT-display and Encoder
TFT-display and Push Buttons
LEDS and Push Button
The production of the full version was cancelled because of a small demand (due to high price and complexity - most of people wants it without TFT display, remote control, volume control and other features)), so the Lite version was developed, which have a great success.
Dr JKILL Lite
Simplified Dr. JKILL version with SPDIF/TOSLINK Input
Can be used as one PCB or splitted to the separate Input PCB and JKill Lite PCB
1 Coax SPDIF Input (transformer coupled)
1 Optical (Toslink) Input
1 Optional Input
4 LED, 4 Pushbutton Input Control
If splitted, JKill Lite PCB have 1 I2S Input,
Sync (MCLK) can be from the DAC or from the optional clock generator (JKill Lite PCB has optional socket)
512*Fs and 1024*Fs External Clocks (optionally - 256 and 384 Fs)
JKill Lite status 3 LED indication
4 inputs control signals/inputs
44.1/48/88.2/96/176.4/192 Sample Rate operation
Short delay time mode for movies
Firmware upgrade form USB Disc-On-KeySmall
100x50 mm PCB, or two 50x50mm PCBS, if splitted.
