MonitorLink DVI Connector

Some manufacturers use DVI-I connectors for DVI- D only. This is the arrangement used by MonitorLink. This configuration will not support analog connections. Therefore, any attempt to in- terface analog signals, no matter what form of DVI- A or DVI-I cables or adaptors used, will not be suc- cessful. Looking at the pin assignments in Table 6, it should become obvious, the DVI-I connector used by MonitorLink is a digital only, single-link TMDS interface.

NOTE: V23 models are compliant with HDCP and EIA861 standards for standard, extended and high definition (480i, 480p, 1080i) video. The DVI input is not intended for use with personal computers or devices outputing video signals with computer resolution.

DVI Input Block Diagram

Figure 13 is a block diagram of the DVI input cir- cuitry used on the V23 Chassis. The circuitry will be similar in other models.

Single-link TMDS Data and Clock signals are ap- plied directly to IC2D00. Vcc for the EEPROM, IC7AAA, is supplied by the host device via the DVI connector, pin 14. At the same time, this potential is fed back to pin 16 for Hot Plug Detection. The host device communicates over the DDC bus directly with the EEPROM to retrieve the EDID. IC2D02 is used to convert the 5V I2C to 3.3V logic for compatibility with IC2D00 where HDCP data is exchanged.

IC2D00 decodes and outputs analog RGB/H/V sig- nals for selection by the TV input select circuitry.
