HagClock Low Jitter Clock Upgrade 3
Description
The HagClock is a high performance clock circuit designed specifically for
upgrading most CD players and transports. Onboard super-regulators provide
ideal power supply conditions for the low phase noise (low jitter) reference
oscillator section. A special output buffer provides accurate transmission of the
clock into your CD player’s circuitry.
HagClock can be mounted inside most transports and taps off of their existing
power supply rails. Requires dealer installation by a qualified technician.

Installation
First, locate the existing crystal within the CD transport. Make sure it is either a
11.2896M or 16.9344M type, and use the appropriate HagClock. Find a location
within the chassis to mount the clock. Place it as close to the existing crystal as
possible. Use the board itself to mark holes for drilling.
Identify the other existing oscillator components by tracing the layout (the circuit
should be as shown in the schematic below). You may have to do a little Internet
research and download the data sheet for the integrated circuit used. This will
help determine the input and output pins, RBIAS, XTAL, CIN, and COUT. Locate
the +/-12V (+/-8V to +/-16V) analog power supplies (they will normally be used
for the opamps in the output stage). The only ground connection will be in the
clock output.
Some transports employ surface mount components. It is easier to remove them
with two soldering irons, one on each side of the component. Save all removed
parts in case you want to restore the transport to its original configuration!
Proceed as follows:
 Remove XTAL, CIN, and COUT.
 Solder one lead of the 100 ohm resistor to the clock input (top of CIN).
 Trim twisted pair output leads as short as possible. Solder the GND lead
to the bottom of CIN, and the ACLK lead to the 100 ohm resistor.
 Solder the VCC wire to +12V, and VEE to –12V.
Testing
Apply power; the LED should immediately light up. Using an oscilloscope,
confirm oscillator action by measuring the output. CD transport should function
normally.

Troubleshooting
Problem Solution
LED does not light up. Correct power not supplied.
CD player locks up. Wrong frequency used? Double check installation.
Could also be that the start-up delay of the
reference oscillator is too long.
