DESCRIPTION (CONTINUED)

The unique multi-functional I/O port of the LMH0031 provides external access to functions and data stored in the

configuration and control registers. This feature allows the designer greater flexibility in tailoring the LMH0031 to

the desired application. The LMH0031 is auto-configured to a default operating condition at power-on or after a

reset command. Separate power pins for the PLL, deserializer and other functional circuits improve power supply

rejection and noise performance.

The LMH0031 has a unique Built-In Self-Test (BIST) and video Test Pattern Generator (TPG). The BIST enables

comprehensive testing of the device by the user. The BIST uses the TPG as input data and includes SD and HD

component video test patterns, reference black, PLL and EQ pathologicals and a 75% saturation, 8 vertical

colour bar pattern, for all implemented rasters. The colour bar pattern has optional transition coding at changes in

the chroma and luma bar data. The TPG data is output via the parallel data port.

The LMH0030, SMPTE 292M / 259M Digital Video Serializer with Ancillary Data FIFO and Integrated Cable

Driver, is the ideal complement to the LMH0031.

The LMH0031's internal circuitry is powered from +2.5 Volts and the I/O circuitry from a +3.3 Volt supply. Power

dissipation is typically 850mW. The device is packaged in a 64-pin TQFP.
