2.5 U502(SiI9187BCNU)

General Description

The SiI9187B HDMI Port Processor is the second generation of HDMI devices that support the HDMI Specification. With four HDMI inputs and a single

output, the SiI9187B port processor enhances the functionality of digital TVs using single system on a chip (SoC) solutions with integrated HDMI

receivers.

The port processor provides a simple, low-cost method of retransmitting digital audio and video to give consumers a truly all-digital experience. Built-in

backward compatibility with DVI 1.0 allows HDMI systems to connect to any DVI 1.0 source.

Features

The SiI9187B device brings cutting edge innovations, such as:

• Enhanced cable equalization for long cable support, even at Deep Color resolutions that enables the SiI9187B device to work with noisy signals and

many sources, making the sink devices highly interoperable

• Integrated EDID and CEC functions

• Improved ESD protection on all signals connected to the HDMI connector.

2.6 U108(MAX3232ECPWR)

General Description

The MAX3232E device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV IEC ESD protection pin to pin (serial-

port connection pins, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an

asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single

3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/ms driver output slew rate.

Features

– ±15 kV (HBM)

– ±8 kV (IEC61000-4-2, Contact Discharge)

– ±15 kV (IEC61000-4-2, Air-Gap Discharge)

· Meets or Exceeds the Requirements of TIA/EIA-232-F and ITU v.28 Standards

· Operates With 3-V to 5.5-V VCC Supply

· Operates up to 250 kbit/s

· Two Drivers and Two Receivers
