DESCRIPTION/ORDERING INFORMATION
The TPD12S015A is an integrated HDMI companion chip solution. This device offers 8 low capacitance ESD
clamps allowing HDMI 1.4 data rates. The 0.4-mm pitch WCSP 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 5V output (5VOUT) for sourcing the HDMI power line. The 5VOUT pin
supplies minimum 55mA 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 non-inverting bi-directional 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 1.1V to
3.6V. On the B side, the SCL_B and SDA_B each have an internal 1.75kΩ pull-up connected to the regulated 5V
rail (5VOUT). The SCL and SDA pins meet the I2C specifications, and drive at least 750pF loads which exceeds
the HDMI cable specification. An LDO generates a 3.3V internal rail for the CEC line operation when LS_OE = H
& CT_CP_HPD = H. The CEC_B pin has a 26kΩ pull-up to this internal 3.3V rail.
The TPD12S015A provides IEC61000-4-2 (Level 4) ESD protection. This device is offered in a space saving
1.6mm × 2.8mm WCSP package.
