Notes:
• There is a GND trench on layer 2 as indicated in the purple dot rectangle. Layer 3 is also
GND. All Blue dots are GND through vias connecting the GND locally among all layers
• The length of two segments (Ha and Hb) is around 1/10 wavelength @ 2.5GHz, which is
about 150 Ω differential HDMI TMDS signal traces above and below the ESD protection
pins. The purpose for these two segments is to compensate the parasitic capacitance
introduced by each ESD protection device pins.
• Ha and Hb might be changed depending on ESD devices used.
The CM2030 HDMI Transmitter Port Protection is designed for next generation HDMI Host
interface protection.
An integrated package provides all ESD, slew rate limiting on CEC line, level
shifting/isolation, overcurrent output protection and backdrive protection for an HDMI port
in a single 38-Pin TSSOP package.
The CM2030 also incorporates a silicon overcurrent protection device for +5V supply voltage
output to the connector.

6.3 Transport Stream Input Ports
The Intel
®
Atom™ processor CE4100 has two Transport Stream (TS) ports, TS0 and TS1.
The interface accepts serial MPEG-2 transport streams. Supported input formats from the
NIM are MPEG-2 Transport Stream (TS) formatted as either DirecTV or DVB. The Intel
®
Atom™ processor CE4100 supports up to two serial external Transport Stream sources
running at the same time.
Note: These two TS ports have same signal interfaces shown in Figure 6-15. If any port is
un
used, all the signals in that port should be left unconnected.
