TDA19978B
Quad HDMI 1.3a receiver with digital processing
8.4 Equalizer
The auto-adaptive equalizer automatically measures and selects the settings which
provide the best signal quality for each cable. This improves signal quality and enables
the use of cable lengths up to 25 m (laboratory tested, contact NXP semiconductors for
detailed information). The equalizer is fully automatic and consequently does not need
any external control.
8.5 Activity detection
The TDA19978B uses activity detection to automatically select the active HDMI input. An
internal, fully programmable, frequency filter controls activity detection. It sees only the
activity on the HDMI inputs with a frequency range between the minimal frequency
(22.5 MHz) and the maximal frequency (205 MHz).
This activity detection can generate an interrupt enabling users to manage each HDMI
input.
8.6 Color depth unpacking
In Deep Color mode, the TDA19978B receives several fragments of a pixel group at the
HDMI link frequency. The color depth unpacking block translates the received pixel group
into pixels at the pixel frequency. This operation is fully automatic and does not need any
external control.
8.7 Derepeater
The HDMI source uses pixel repetition to increase the transmitted pixel clock frequency
for transmitting video formats at native pixel rates below 25 Mpixel/s or to increase the
number of audio sample packets in each line. The derepeater function discards repeated
pixels and divides the clock to reproduce the native video format.
8.8 Upsample
The HDMI source can use YCbCr 4:2:2 pixel encoding which enables the number of bits
allocated per component to be increased up to 12. The upsample function transforms this
12-bit YCbCr 4:2:2 data stream into a 12-bit YCbCr 4:4:4 data stream by repeating or
linearly interpolating the chrominance pixels Cb and Cr.
Upsampling mode is selected using the I2C-bus.
8.9 Packet extraction
Information sent during the Data Island periods is extracted from the HDMI data stream.
Audio clock regeneration, general control and InfoFrames can be read using the I2C-bus
while audio samples are sent to the audio FIFO.
The TDA19978B can receive HDMI 1.3a packets, general control and color gamut
metadata packets.
In audio applications, the TDA19978B manages HBR packets for high bit rate
compressed audio streams (IEC 61937), OBA samples and DST packets for one bit audio
and SACD with DSD and DST audio streams.
