As many are asking: What if I've already installed one of the not-so-EZ clocks and removed parts from my motherboard?
Yes replacing removed surface mount parts especially can evoke some or all of pain, fear and loathing.
If you have already installed clocks the "hard way" we recommend using "XO" output and wiring the clock signal directly to the clock pin, basically the same way you have previously connected the clock.
But just soldering in the XTal adapter in the place of the original crystal with non of the removed parts replaced will be fine too.

“The Clock”
Super Regulators
There are two “Super Regulators” on “The Clock”. One Super Regulator powers the clock circuit, the other power the special unique buffer section.
The regulators use very low noise operational amplifiers, offering a noise performance near the limits of what can be achieved without permanently super cooling the circuit in liquid nitrogen.
The Super Regulators also uses the lowest noise voltage reference available (LM329), offering 75nV|/Hz noise performance.
This ultra low noise voltage reference is used together with a two-stage low pass, which filters the noise from the reference by a factor of 100 at 1Hz and by a factor of 2500 at 10Hz
The combination makes the lowest noise reference possible for the Super Regulators.
More crucially, this performance is maintained even at very low frequencies ( < 10Hz). It is the very low frequency noise that tends to dominate jitter in a well designed clock and is very hard to control.
Unique buffered output
Any clock oscillator’s performance is degraded when being asked to directly drive logic inputs, circuit traces and wiring, some oscillators will not even work at all if loaded too much.
Fitting high current, high impedance buffers within millimeters after “The Clock” ensures “The Clock” oscillator operates without any significant load at all.
The result is a clock where the theoretical performance of “The Clock” oscillator is realised as it operates into a load and with a power supply that is as close to theoretically perfect as can be made.
The Output Buffer drives two separate outputs, one a special circuit that emulates the normal clock crystal found in most players and another that offers an output compatible with the less common 4-Pin “canned oscillator” type.
The Crystal Emulation output is not designed to source or sink significant currents.
The XO type output can drive up to +/-10mA.
“The Power”
Despite being rated at a low 1.2VA output (12V/0.1A), “The Power” uses an oversized 6VA transformer.
The transformer is fitted with a special electrostatic screen to ensure lowest noise possible.
It uses Full Wave Rectification (not bridge) with two noiseless schottky diodes. It uses chokes filter on the input.
It uses a CRCRC power supply filter with 3,000uF total capacitance.
It uses a special low noise 12V regulator. The Circuit Design in “The Power” parallels that of a power supply used for a high-end tube preamp, but scaled to the appropriate voltages for “The Clock”.

Attached photo shows a Marantz CD-80 done right with the EZ Ultimate Clock System. No sense using a non-pedigreed CDP.
The original clock crystal was “fixed up” on the same socket used by the EZ Ultimate Clock so we could plug in one or the other for quick and convincing comparison.
The EZ Ultimate Clock System was a significant improvement, despite the fact that clock still needs to go through the SAA7220 as we used the “crystal emulation” mode (EZ installation).
Photo shows the CD-80, also with the UTS installed and with the Clock & Supply fitted.
The UTS too provided a major upgrade over the original analog stage, despite being already fitted OPA627 Op-Amp’s and many other upgrades including Elna Silmic Caps and Sanyo Os-Cons (as you can see).
The CD-80 with both of these is a majorly nice CD-Player.

Good engine needs good road or the potential is unrealized. Same with The Clock -- much of the benefit is impeded if it has to function in a bumpy electrical stream.
The Power module is the strongly recommended companion to The Clock Module. 45mm x 95mm and completes the package.

First - the pcb is small 30 x 60mm, much smaller than existing clocks. It's well-populated with surface mounted devices on both sides of the pcb but purposely designed to have a small footprint.
Advantages:
1. digital signal is tightly confined which avoids spraying analogue signal components with toxic digital noise
2. easy to mount! only 30 x 60mm
Second - the clock module includes 3 snap-off adapters which makes comparing clocks and installation a walk in the park. Just install the right socket (DIP8, 14 or OSC native 2 pin) on your mainboard and after that - plug n play!
Third - no surgery needed on your existing mainboard. At most just a socket installation
Fourth - The DIYHFS OSC itself is selected not only for extremely low jitter, but also for phase integrity. They will be available to purchase separately.
DIY - Done Right!
