TDA9981B

150 MHz pixel rate HDMI transmitter

8.

Functional description

The TDA9981B is designed to convert digital data (video and audio) into an HDMI or a

DVI stream. This HDMI stream can handle RGB, YCbCr 4:4:4 and YCbCr 4:2:2. The

TDA9981B can accept at its inputs any of the following video modes:

• RGB

• YCbCr 4:4:4

• YCbCr 4:2:2 semi-planar

• YCbCr 4:2:2 ITU656 and ITU656-like

It can also handle audio. The TDA9981B can accept at its inputs any of the following audio

buses:

• I2S-bus (4 lines): up to 8 audio channels

• S/PDIF (1 channel): L-PCM (IEC 60958) or compressed audio (IEC 61937)

8.1 System clock

The clock management is based on a set of two PLLs that generate the different clocks

required inside the chip:

• PLL double edge can generate a clock at twice the VCLK input frequency to capture

the data at the video input formatter.

• PLL serializer is a system clock generator, which enables the stream produced by the

encoder to be transmitted on the HDMI data channel at ten times the sampling rate or

more; see Section 8.14.2.

8.2 Video input processor

The TDA9981B has three video input ports VPA[7:0], VPB[7:0] and VPC[7:0].

The TDA9981B can reallocate and swap each of the 3 input channel ports by inverting the

bus and swapping each port.

The TDA9981B can be set to latch data at either the rising or falling edge or both.

The video input formats accept (see Table 5):

• RGB

• YCbCr 4:4:4 (up to 3

× 8-bit)

• YCbCr 4:2:2 semi-planar (up to 2

× 12-bit)

• YCbCr 4:2:2 compliant with ITU656 and ITU656-like (up to 1

× 12-bit)
