General Description
The LMH0030 SMPTE 292M/259M Digital Video Serializer with Ancillary Data FIFO and Integrated Cable Driver is a monolithic
integrated circuit that encodes, serializes and transmits bit-parallel digital video data conforming to SMPTE 125M and 267M
standard definition, 10-bit wide component video and SMPTE 260M, 274M, 295M and 296M high-definition, 20-bit wide component
video standards. The LMH0030 operates at SMPTE 259M serial data rates of
270 Mbps, 360 Mbps, the SMPTE 344M serial data rate of 540 Mbps, and the SMPTE 292M serial data rates of 1483.5 and 1.485 Gbps. The
serial data clock frequency is internally generated and requires no external frequency setting, trimming or filtering components.
The LMH0030 performs functions which include: parallel-to-serial data conversion, SMPTE standard data encoding, NRZ to NRZI
data format conversion, serial data clock generation and encoding with the serial data, automatic video rate and format detection,
ancillary data packet management and insertion, and serial data output driving. The LMH0030 has circuitry for automatic EDH/CRC
character and flag generation and insertion per SMPTE RP-165 (standard definition) or SMPTE 292M (high definition). Optional
LSB dithering is implemented which prevents pathological pattern generation. Unique to the LMH0030 are its video and ancillary
data FIFOs. The video FIFO allows the video data to be delayed from 0 to 4 parallel data clock periods for video timing purposes.
The ancillary data port and on-chip FIFO and control circuitry store and insert ancillary flags, data packets and checksums
into the ancillary data space. The LMH0030 also has an exclusive built-in self-test (BIST) and video test pattern generator
(TPG) with SD and HD component video test patterns: reference black, PLL and EQ pathologicals and color bars in 4:3 and 16:9
raster formats for NTSC and PAL standards*. The color bar patterns feature optional bandwidth limiting coding in the chroma
and luma transitions.
The LMH0030 has a unique multi-function I/O port for immediate access to control and configuration settings. This port may
be programmed to provide external access to control functions and indicators as inputs and outputs. The designer can thus
customize the LMH0030 to fit the desired application. At power-up or after a reset command, the LMH0030 is auto-configured
to a default operating condition. Separate power pins for the output driver, PLL and the serializer improve power supply
rejection, output jitter and noise performance.
The LMH0030's internal circuitry is powered from +2.5V and the I/O circuitry from a +3.3V supply. Power dissipation is typically
430mW at 1.485 Gbps including two 75Ω AC-coupled and back-matched output loads. The device is packaged in a 64-pin TQFP.

Note: The Early Failure Rates were calculated as point estimates. The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
