Description The LMH0384 3 Gbps HD/SD SDI Extended Reach and Configurable Adaptive Cable Equalizer is designed to equalize data transmitted
over cable (or any media with similar dispersive loss characteristics). The equalizer operates over a wide range of data
rates from 125 Mbps to 2.97 Gbps and supports SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M standards.
The LMH0384 includes active sensing features and design enhancements including longer cable equalization, lower output jitter,
configurable pin mode and SPI modes, a power-saving sleep mode, and programmable output common mode voltage and swing. The
LMH0384 implements DC restoration to correctly handle pathological data conditions.
The LMH0384 includes an auto sleep mode to power down the device when no input signal is detected. Other features include
separate carrier detect and output mute pins which may be tied together to mute the output when no input signal is present,
and a programmable mute reference which may be used to mute the output at a selectable level of signal degradation.
The LMH0384 supports two modes of operation. In pin mode (non-SPI mode) the LMH0384 is footprint compatible with the LMH0344
and legacy SDI equalizers. In the optional SPI mode, the LMH0384 provides register access to all of its features along with
a cable length indicator, programmable output common mode voltage and swing, and launch amplitude optimization.
The device is available in a 16-pin LLP package.

SD384SPIEVK
| SD384SPIEVK - Evaluation Board for LMH0384 Cable Equalizer with SPI Interactive GUI | Preliminary
| | Distributor | Region | Qty |
| NATIONAL |  | United States | 5 |
| CALL | N/A |
Description:
The SD384SPIEVK is an evaluation kit designed to demonstrate the performance and capabilities of the LMH0384 3 Gbps HD/SD SDI Extended Reach and Configurable Adaptive Cable Equalizer.
The board accepts 75Ω input signals conforming to the SMPTE 424M, SMPTE 292M, or SMPTE 259M standards. The LMH0384 will restore the input signal after it has been attenuated by coaxial cable. The LMH0384 differential output is provided via two 50Ω SMA connectors. Jumpers on the board can be configured for evaluation of LMH0384 features such as auto sleep, carrier detect, mute, bypass, and SPI mode / pin mode select.
The SD384SPIEVK includes a USB interface to connect to a host PC. The Analog LaunchPAD (ALP) software application allows managing the SPI registers of the LMH0384. It provides easy control and monitoring of device features such as: output swing and offset adjustment, input launch level optimization, sleep mode, mute, bypass, extended 3G reach mode, and cable length indicator. The software is available for download here.(zip 20.9MB).

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
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.
