1. 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
2.25 gigasamples per second. In addition, the TDA19978B is delivered with software
drivers to ease configuration and use.
The TDA19978B supports:
The TDA19978B includes:
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 t
addition, all settings are controllable using the I
