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 (TLGA).
