Source Spread Spectrum Clocking (SSC) Differential Tests (Normative & Informative) 13

Agilent U7232A DisplayPort Electrical Performance Compliance Test Application 119

Test Pattern: D10.2.

SSC: Enabled. The devices that do not have SSC Enabled will not be

tested.

An evaluation of at least 10 full SSC cycle is required.

SSC Deviation HF Variation Test Condition

Bit Rate: highest rates are supported.

Output Level: 800 mVolts.

Pre- Emphasis: 0 dB.

Test Pattern: D10.2.

SSC: Enabled. The devices that do not have SSC Enabled will not be

tested.

An evaluation of at least 10 full SSC cycle is required.

SSC Modulation Frequency PASS Condition

The SSC Modulation Frequency result must satisfy the following criteria:

• f

SSC

measures between 30 kHz and 33 kHz

The value above shall be based on a mean of at least 10 complete SSC

cycles.

SSC Modulation Deviation PASS Condition

The SSC Modulation Deviation result must satisfy the following criteria:

• SSC

tol

measures between 5000 ppm and 0 ppm

The value above shall be based on a mean of at least 10 complete SSC

cycles.

SSC Deviation HF Variation PASS Condition

The SSC Deviation HF Variation result must satisfy the following criteria:

• SSCt dF/dt ≤ 1250 ppm/µSec variations

The value above shall be based on a mean of at least 10 complete SSC

cycles.
