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 1.75k

Ω 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.
