3G HD/SD SDI configurable I/O adaptive cable equalizer / cable driver

The LMH0387 3Gbps 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 use the flexibility to use a BNC

attached to the device as either an input or an output.

The device operates over a wide range of data rates from 125Mbps to 2.97Gbps (DC to

2.97Gbps when driving cable) and supports ST 424, ST 292, ST 344, and ST 259. The

return loss network is integrated within the device so no external components are

required to meet the SMPTE return loss specification. The LMH0387 offers designers

flexibility in system design and quicker time to market.

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. In the output mode, the

LMH0387 features include two selectable slew rates for ST 424 / 292 and ST 259

compliance, and output driver power-down control.

The device is available in a 7mm × 7mm 48-pin laminate thin laminate grid array

(TLGA) package.
