There are three non-inverting bi-directional translation circuits for the SDA, SCL, and CEC lines. Each have a
common power rail (V
CCA
) 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 pullup connected to the regulated 5 V rail (5VOUT). The SCL and SDA pins meet the I
2
C
specification and drive up to 750 pF loads. The CEC_B pin has an internal 27 kΩ pullup to an internal 3.3 V
supply.
The HPD_B port has a glitch filter to avoid false detection due to the bouncing while inserting the HDMI plug.
The TPD12S015 provides IEC61000-4-2 (Level 4) ESD protection. This device is offered in a space-saving 1.6
mm × 2.8 mm wafer-level chip scale package [WCSP (YFF)] with 0.4-mm pitch.
