TDA19978A
Quad HDMI 1.3a receiver with digital processing
2. Features and benefits
Complies with the HDMI 1.3a, DVI 1.0, CEA-861-D and HDCP 1.2 standards
Four (quad) independent HDMI inputs, up to the HDMI frequency of 205 MHz
Embedded auto-adaptive equalizer on all HDMI links
EDID memory: 253 shared bytes and three bytes dedicated to each HDMI input
Supports color depth processing (8-bit, 10-bit or 12-bit per color)
Color gamut metadata packet with interrupt on each update, readable via the I2C-bus
Up to four S/PDIF or I2S-bus outputs (eight channels) at a sampling rate up to 192 kHz
with IEC 60958/IEC 61937 stream
HBR audio stream up to 768 kHz with four demultiplexed S/PDIF or I2S-bus outputs
HBR streams (e.g. DTS-HD master audio and Dolby TrueHD up to eight channels due
to HBR packet for stream with a frame rate up to 768 kHz) support
DSD and DST audio stream up to six DSD channels output for SACD with DST Audio
Packet support
Channel status decoder supports multi-channel reception
Improved audio clock generation using an external reference clock
System/master clock output (128/256/512 × fs) enables the use of the UDA1334BTS
The HDMI interface supports:
All HDTV formats up to 1920 × 1080p at 50/60 Hz and WUXGA (1920 × 1200p at
60 Hz) with support for reduced blanking
PC formats up to UXGA (1600 × 1200p at 60 Hz)
Embedded oscillator (an external crystal can be used)
Frame and field detection for interlaced video signal
Sync timing measurements for format recognition
Improved system for measurements of blanking and video active area allowing an
accurate recognition of PC and TV formats
HDCP with repeater capability
Embedded non-volatile memory storage of HDCP keys
Programmable color space input signal conversion from RGB-to-YCbCr or
YCbCr-to-RGB
