TPD12S015A EVM
Introduction
The TPD12S015A is an integrated HDMI
companion chip solution. The device pin mapping
matches the HDMI Type D or Type C connector
with four differential pairs. This device offers 8 low
capacitance ESD clamps allowing HDMI 1.4 data
rates. The integrated ESD clamps and resistors
provide good matching between each differential
signal pair. This provides an advantage over
discrete ESD clamp solutions where variations
between ESD clamps degrade the differential
signal quality.
The TPD12S015A provides a regulated 5V output
(5VOUT) for sourcing the HDMI power line. The
regulated 5V output supplies up to 55mA to the
HDMI receiver. The control of 5VOUT and the hot
plug detect (HPD) circuitry is independent of the
LS_OE control signal and is controlled by the
CT_CP_HPD pin. This independent control
enables the detection scheme (5VOUT + HPD) to
be active before enabling the HDMI link.
