TDA19978AHV/15/C18

1. General description
The TDA19978A is a four input HDMI 1.4a 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 (laboratory tested with a 0.5 mm (24 AWG) cable at
2.05 gigasamples per second). The HDCP key set is stored in non-volatile One Time
Programmable (OTP) memory for maximum security. In addition, the TDA19978A is
delivered with software drivers to ease configuration and use.
The TDA19978A 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, One Bit Audio (in SACD), DST (in compressed DSD) and HBR
stream
The TDA19978A includes:
An enhanced PC and TV format recognition system
Generation of a 128/256/512 × f
s
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
One Bit Audio (in SACD), DST (in compressed DSD) and HBR stream support
The TDA19978A converts HDMI streams with or 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 for t
su(Q)
and t
h(Q)
. In
addition, all settings are controllable using the I
2
C-bus.
