A. 1ppm TCXO Oscillator
1. Fit the 1ppm TCXO oscillator into ‘The Clock” oscillator socket (Y1).
Note: 
  • Observe orientation. Pin 1 of the TCXO oscillator shall align with the square corner of the silk print. 
  • UNDER NO CIRCUMSTANCES attempt to re-adjust the oscillator by yourself. 
B: “The Clock” 
1. Choose the adapter that fits your application:
a. 2-pin crystal – use 2 pin adapter
b. 4-pin oscillator DIP 8 Type (square) – use XO DIP8 Adapter
c. 4-pin oscillator DIP 14 Type (rectangular) – use XO DIP14 Adapter
Note: 
  • Three different adapters are attached to ‘The Clock”. Break these off carefully using a small set of pliers and select the one that matches the clock you are replacing. 
  • You may wish to keep the remaining adapters for future use. 
2-pin crystal adapter 
1. Unsolder the original crystal (2-pin).
2. Solder the 2-pin crystal adapter in place (non-directional).
3. Connect the supplied cable between the “Adapter XTAL” socket (P3) on ‘The Clock” and the socket on the 2-pin crystal adapter.
Note: 
  • The “Adapter XTAL” socket (P3) on ‘The Clock” is used with the 2-pin crystal adapter
4-pin oscillator (DIP 8-pin and DIP 14-pin) adapter 
1. Unsolder the original Oscillator (4-pin).
2. Solder the 4-pin oscillator adapter (XO DIP8 or XO DIP14) in place (pin 1 must be correctly positioned).
3. Connect the supplied cable between the “Adapter XO” socket (P2) on ‘The Clock” and the socket on the 4-pin oscillator adapter.
4. Set the output voltage of ‘The Clock” by the jumper (J1) on ‘The Clock”. Default is 5V.
5. Connect ‘The Clock” module to “The Power” using suitable cables.
Note: 
  • The “Adapter XO” socket (P2) on ‘The Clock” is used with the 4-pin oscillator adapter. 
  • Usually, older players will require 5V clock, many newer players and most DVD Players will need a 3.3V clock however. If in doubt consult the service manual and/or the manufacturer’s datasheet or measure the supply voltage of the existing oscillator by the following methods: 
    • „ Measure the voltage between pin-4 and pin-8 on the DIP8 modules 
    • „ Measure the voltage between pin-7 and pin-14 on the DIP14 modules 
  • The power supply to ‘The Clock” should be at least 10V DC, no more than 16V DC (100mA). The matching ultra low noise power supply “The Power” is highly recommended in order to get the best performance out of “The Clock”. 
  • If the LED (D3) on “The Power” lights up, but that LED (D2) on ‘The Clock” does not, most likely “The Power” connections are connected incorrectly. 

C. “The Power”

1. Mains connection:

230V Connection 
  • Connect L2 to N1 (short jumper wire)
  • Connect mains Live to L1
  • Connect mains Neutral to N2
  • Connect Earth to Earth; if no Earth is presented, connect via 0.1uF/100V to chassis.
115V Connection 
  • Connect L1 to L2 (short jumper wire)
  • Connect N1 to N2 (short jumper wire)
  • Connect Live to L1
  • Connect Neutral to N2
  • Connect Earth to Earth, if no earth is presented, connect via 0.1uF/100V to chassis.

Note: 
  • Only use suitable, mains rated wire with the “The Power”. 
  • Be careful to isolate the mains at the take off point in the CD-Player. 
  • Take care to preserve the insulation requirements for your specific device (Electrical Safety)

 

2. “The Clock” to “The Power” connection:

  • Connect “The Power” + to “The Clock” +
  • Connect “The Power” – to “The Clock” –

EZ Ultimate Clock System

“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”.
