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.
