    • Description

    The LMH0387 3 Gbps HD/SD SDI Configurable I/O Adaptive Cable Equalizer / Cable Driver provides a single chip interface to a BNC. The device can be configured either in the input mode as an equalizer to receive data over coaxial cable or in the output mode as a cable driver to transmit data over coaxial cable. The same I/O pin is used both for the input and the output functions of the device, allowing the system designer the flexibility to use a BNC attached to the device as either an input or an output.

    The LMH0387 offers designers flexibility in system design and quicker time to market. The device operates over a wide range of data rates from 125 Mbps to 2.97 Gbps (DC to 2.97 Gbps when driving cable) and supports SMPTE 424M, SMPTE 292M, SMPTE 344M, and SMPTE 259M. The return loss network is integrated within the device so no external components are required to meet the SMPTE return loss specification.

    In the input mode, the LMH0387 features include a power-saving sleep mode, programmable output common mode voltage and swing, cable length indication, launch amplitude optimization, input signal detection, and an SPI interface. In the output mode, the LMH0387 features include two selectable slew rates for SMPTE 424M / 292M and SMPTE 259M compliance, and output driver power down control.

    The device is available in a 7 x 7 mm 48-pin laminate Thin Chip Scale Package (TCSP).

    Description:

    The SD387EVK is an evaluation kit designed to demonstrate the performance and capabilities of the LMH0387 3 Gbps HD/SD SDI Configurable I/O Adaptive Cable Equalizer / Cable Driver.

    The SD387EVK has two primary modes of operation. In the input mode, the board accepts 75Ω input at the BNC conforming to the SMPTE 424M, SMPTE 292M, or SMPTE 259M standards. The LMH0387 will restore the input signal after it has been attenuated by coaxial cable, and provide a differential output via two 50Ω SMA connectors. In the output mode, the board accepts differential input via two 50Ω SMA connectors and drives 75Ω coaxial cable via the BNC. Jumpers on the board can be configured for evaluation of LMH0387 features such as the equalizer carrier detect, cable driver SD/HD, and cable driver TX_EN.

    The SD387EVK includes a USB interface to connect to a host PC. The Analog LaunchPAD (ALP) software application allows managing the SPI registers of the LMH0387 equalizer. It provides easy control and monitoring of equalizer features such as: output swing and offset adjustment, input launch level optimization, sleep mode, mute, extended 3G reach mode, and cable length indicator. The software also allows control of the LMH0387`s I/O mode. The software is available for download here.(zip 22.5MB).

    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.
