is a single chip solution that converts four channels
of analog video to YCbCr digital component video. The power of the
XR5P920 lies in its ability to accept a wide range of input formats
including the new high-definition (HD) analog standard, HDCVI,
as well as the standard-definition (SD) formats of NTSC, PAL and
widescreen 960H. The four-output channels of the XR5P920 conform
to the SMPTE and ITU-R digital HD standards up to 1080p30 or
720p60 in addition to the digital SD standards. Each video channel
offers independent brightness, contrast, sharpness, gain, white-peak
control, hue and saturation adjustment.
The XR5P920 effectively decodes video from over 500-m of coaxial
cable with the aid of an internal equalizer which compensates for high-
frequency signal attenuation. Following equalization, the video from
each channel is processed through an analog front end (AFE) that
provides clamping, programmable gain amplification and analog-to-
digital conversion (ADC). Each video output supports time division
multiplexing (TDM) two channels of HD video or up to four channels
of SD video. The XR5P920 also has the flexibility to provide a mixed
mode output that multiplexes both HD and SD video onto one or all
four channels.
Additional features include an I
2
S interface that allows for audio record
and playback, a simple communication protocol enabling two-way
control and a 400 kHz I
2
C interface for CPU or MCU interconnect.
Audio is processed with 16-bit pulse code modulation (PCM) that
enables up to five channels of high quality audio input.
