INDEPENDENT OUTPUTS

6 × BNC

10MHz clock reference.

3 × Sine

2 × 50Ω + 1 × 75Ω

3 × Square

2 × 50Ω + 1 × 75Ω

Independent drivers and transformer isolation for all six outputs. Default impedances shown.

CLOSE-IN PHASE NOISE

≤−110

Better than −110 dBc at 1Hz offset.
Typical · SC-cut OCXO.

<5ppb stability.
<0.05ppm accuracy.

LINEAR POWER

3 power rails.

LT3042 + PNP
Separate regulation for the OCXO, mainboard and tuning reference.

Talema transformer.
EMI and CLC filtering.

OUTPUT GROUND CONTROL

6 ground
switches.

Connect or isolate each output’s signal ground from the clock’s signal ground.

Separated circuit compartments.
CNC-machined aluminum keeps functional sections apart.

Includes an OCXO phase-noise and Allan deviation test report.
