The Clock and The Power

Yes we are late to the party. We have wanted a clock/ps module for some time but held back due to the extensive documentation required and, we wanted something decisively better - the best.

So ... we present the world's easiest-to-install, ultimate performance digital clock and power supply system:

The Clock and The Power:

Base Features:
• Simple Pin-to-pin direct drop-in replacement for any CD/DVD player Clock Crystal (2-Pin)
• Simple drop-in replacement of oscillator modules (4-Pin)
• +/- 1pm accuracy
• 3V / 5V output level setting on board
• Unique clock circuit with ultra-low jitter < 1.5 ps RMS
• On-Board ultra-low noise, ultra-low impedance, wide bandwidth Super Regulator
• LED Voltage monitor
• Maxi-Design, choke filtered Power Supply Module included
• Gold plated, 70 micron Copper PCB
Specification:
Accuracy: +/- 1ppm
Jitter: 1.5ps
Clock Output: Direct or isolated (selectable)
Power Supply Req.: 115V/230V AC with Power Supply Module
12V DC/50mA without Power Supply Module
Frequencies Available: 11.289600 MHz (CDP – most Philips Chipsets)
12.000000 MHz (USB Audio)
16.934400 MHz (CDP – most Sony/Sanyo Chipsets)
24.576000 MHz (96/192kHz upsamplers e.g. CS8420)
27.000000 MHz (DVD/SACD/Universal Players)

Hi bcherry ,
with what eqiupment you find out the jitter size in ps?

Manufacturer's data for the TCXO. We have the TCXO made and selected for best phase performance and lowest jitter. They test and provide the data sheet with the product but we don't know what equipment they use to test.
The circuit itself is designed for lowest noise and not the limiting factor.

I see,I am just heard from Vil the creator of lessloss dac,that to find out less when 30 ps jitter requires very expensive tool,so I dont know
thnx.

[bcherry]

Yes it is true.
Maybe only a manufacturer of TCXO would keep such equipment on hand. A trustworthy manufacturer provides the data sheet with measurements for each unit, as does ours.

So you measure the clock jitter, do you measure the jitter of the clock and pcb as inserted into another piece of kit? Surely the TCXO is only as good as the implementation..

Hint: its not impossible to find Aeroflex measurement system, I know of one that can be approached. Then you have nice plots like those of DDS IC datasheets, down to 10hz.

Yes true. However inserting the clock pcb into another pc of kit would add it's own variables. We don't have the specialized testing equipment to do a direct measurement, however the PS has less than uV of noise so the limiting factor is the TCXO itself. The manufacturer provides us with the test data for each unit of TCXO. In fact the majority test <1ps.

Hi BCherry,
Could you share with us how much each module cost? I mean the clock and the PS module separately? Many Thanks!

180USD for the clock and $90USD for the PS.
