3 Description
TVB1440 is a 4 channel re-driver signal conditioner
for TV applications allowing signal integrity between
TV chipset and TCON boards. I²C control provides
the wide ranges of flexibility to configure the device
for optimal signal conditioning so that video data link
between a source and sink can achieve high fidelity.
TVB1440 allows larger distance between a video
source and sink device through its excellent jitter
cleaning capability.
It has selectable control for receive equalization
accessible through I2C to compensate for large trace
or cable loss at its input resulting improved eye at the
output signals. Transmitter in each channel has 4
levels of pre-emphasis and 4 levels of output voltage
swing settings which enable optimum video signal
performance from the TVB1440 to downstream
receiver.
The TVB1440 is optimized for power conscience
applications. Apart from its low active power,
TVB1440 contains activity detection circuitry on the
data link input that transitions to a low-power output
disable mode in the absence of a valid input signal.
This activity detect circuit can be disabled if desired.
The device also has a shutdown mode when
exercised results in 2mW.
