DESCRIPTION

The TPD12S016 is a single-chip HDMI interface device with auto-direction sensing I2C voltage level shift buffers,

load switch, and integrated high-speed ESD protection clamps. The device pin mapping matches the HDMI Type

D connector with four differential pairs. This device offers eight low-capacitance ESD clamps, allowing HDMI 1.4

data rates. The integrated ESD circuits provide good matching between each differential signal pair, which allows

an advantage over discrete ESD solutions where variations between ESD protection clamps degrade the

differential signal quality. The TPD12S016 provides a current limited 5 V output (5V_OUT) for sourcing the HDMI

power line. The current limited 5 V output supplies up to 55 mA to the HDMI receiver. The control of 5V_OUT

and the hot plug detect (HPD) circuitry is independent of the LS_OE control signal, and is controlled by the

CT_HPD pin. This independent CT_HPD control enables the detection scheme (5V_OUT and HPD) to be active

before enabling the HDMI link. An internal 3.3V node powers the CEC pin eliminating the need for a 3.3V supply

on board.

The TPD12S016 integrates all the external termination resistors at the HPD, CEC, SCL, and SDA lines. There

are three non-inverting bi-directional translation circuits for the SDA, SCL, and CEC lines. Each have a common

power rail (VCCA) on the A side from 1.1 V to 3.6V. On the B side, the SCL_B and SDA_B each have an internal

1.75 kΩ pull up connected to the 5 V rail (5V_OUT). The SCL and SDA pins meet the I2C specification and drive

up to 750 pF capacitive loads exceeding the HDMI1.4 specifications. The CEC_B pin has an internal 27 kΩ pull

up to the internal 3.3 V supply rail. The HPD_B port has a glitch filter to avoid false detection due to plug

bouncing during the HDMI connector insertion.

The TPD12S016 offers reverse current block feature at the 5V_OUT pin. In the fault conditions, such as when

two HDMI transmitters connect to the same HDMI cable, the TPD12S016 ensures that the system is safe from

powering up through external HDMI transmitter. The Dx, CLKx, SCL_B, SDA_B, CEC_B pins also feature

reverse-current blocking when the system is powered off.
