General description
The TDA9975A is a combination of an analog video interface and a High-Denition
Multimedia Interface (HDMI) receiver. The analog video interface comprises three 10-bit
video converters, each converter having triple inputs. The HDMI receiver has two inputs
and an embedded High-bandwidth Digital Content Protection (HDCP) keys memory.
The IC converts a YUV (YPBPR) analog signal into a YUV (YCBCR) or RGB digital signal
or converts an RGB analog signal into a RGB or YUV (YCBCR) digital signal with a
sampling rate up to 81 Msample/s.
The IC supports analog TV resolutions from 480i (720
× 480i at 60 Hz) and 576i
(720
× 576i at 50 Hz) to HDTV (up to 1920 × 1080i at 50/60 Hz) and analog PC
resolutions from VGA (640
× 480p at 60 Hz) to XGA (1024 × 768p at 75 Hz).
The IC can also convert an HDMI stream (with or without HDCP) into a RGB or YUV
(YCBCR) digital signal with a sampling rate up to 81 Msample/s.
The YCBCR digital output signal can be 4 : 4 : 4 or 4 : 2 : 2 semi-planar format following
the ITU-R BT.601 standard or 4:2:2 ITU-R BT.656 format.
All settings are controllable via the I2C-bus.
