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.
