TPD12S015A EVM Layout
The TPD12S015A EVM has been designed for HDMI functional testing and includes both HDMI A-type and
HDMI C-type connectors. Board jumpers enable and disable the dc-dc and level shifting circuitry. There are two
supply terminals (VCCA and VBAT) and one GND terminal at the edge of the board. High speed lines were kept
on top and bottom layers and matched for 50 Ω line to GND. All the high speed lines are matched to minimize
the skew. The board has three test fixtures for testing the TPD12S015A in the following environments:
• The top segment enables system designers to test the TPD12S015A using the HDMI Class A connector
• The middle segment enables the system designers to test to test the TPD12S015A using the HDMI Class C
connector
• The bottom segment enables the system designers to test signal integrity and eye pattern using differential
probe.
