General description

The TDA19978B is a four input HDMI 1.3a compliant receiver with embedded EDID

memory. The built-in auto-adaptive equalizer improves signal quality and allows the use of

cable lengths up to 25 m which are laboratory tested with a 0.5 mm (24 AWG) cable at

2.05 gigasamples per second. In addition, the TDA19978B is delivered with software

drivers to ease configuration and use.

The TDA19978B supports:

• TV resolutions:

– 480i (1440

× 480i at 60 Hz), 576i (1440 × 576i at 50 Hz) to HDTV (up to

1920

× 1080p at 50/60 Hz)

– WUXGA (1920

× 1200p at 60 Hz) reduced blanking format

• PC resolutions:

– VGA (640

× 480p at 60 Hz) to UXGA (1600 × 1200p at 60 Hz)

• Deep Color mode in 10-bit and 12-bit (up to 205 MHz TMDS clock)

• Gamut boundary description

• IEC 60958/IEC 61937, OBA (One Bit Audio), DST (Direct Stream Transfer) and HBR

(High Bit Rate) stream

The TDA19978B includes:

• An enhanced PC and TV format recognition system

• Generation of a 128/256/512 × fs system clock allowing the use of simple audio DACs

without an integrated PLL (such as the UDA1334BTS)

• An embedded oscillator (an external crystal can also be used)

• Improved audio clock generation using an external reference clock

• OBA (as used in SACD), DST and HBR stream support

The TDA19978B converts HDMI streams without HDCP into RGB or YCbCr digital

signals. The YCbCr digital output signal can be 4:4:4 or 4:2:2 semi-planar format based

on the ITU-R BT.601 standard or 4:2:2 based on the ITU-R BT.656 format. The device can

adjust the output timing of the video port by altering the values of tsu(Q) and th(Q). In

addition, all settings are controllable using the I2C-bus.
