3 Description
The TPD12S015A device is an integrated HDMI
companion chip solution. This device offers 8 low
capacitance ESD clamps allowing HDMI 1.3/1.4 data
rates. The 0.4-mm pitch DSBGA package pin
mapping matches the HDMI Type D or Type C
connectors. The integrated ESD clamps in monolithic
silicon technology 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 5-V output
(5VOUT) for sourcing the HDMI power line. The
5VOUT pin supplies minimum 55 mA to the HDMI
receiver while meeting the HDMI 5VOUT
specifications. The 5VOUT and the hot plug detect
(HPD) circuitry are independent of the LS_OE control
signal; they are controlled by the CT_CP_HPD pin.
This independent control enables the detection
scheme (5VOUT + HPD) to be active before enabling
the HDMI link. The HPD_B port has a glitch filter to
avoid false detection due to the bouncing while
inserting the HDMI plug.
There are three noninverting bidirectional translation
circuits for the SDA, SCL, and CEC lines; they are
controlled by the LS_OE control signal. Each have a
common power rail (VCCA) on the A side from 1.1 V
to 3.6 V. On the B side, the SCL_B and SDA_B each
have an internal 1.75-kΩ pullup connected to the
regulated 5-V rail (5VOUT). The SCL and SDA pins
meet the I2C specifications, and drive at least 750-pF
loads which exceeds the HDMI cable specification.
An LDO generates a 3.3-V internal rail for the CEC
line operation when LS_OE = H & CT_CP_HPD = H.
The CEC_B pin has a 26-kΩ pullup to this internal
3.3-V rail.
The TPD12S015A provides IEC61000-4-2 (Level 4)
ESD protection. This device is offered in a spacesaving
1.56-mm × 2.76-mm DSBGA package.
