GF9330 High Performance
HDTV/SDTV Deinterlacer
GF9330 Data Sheet
Device Overview
The GF9330 is a 10-bit high performance VDSP engine that
performs high quality motion adaptive de-interlacing of
interlaced digital video signals. The GF9330 supports
standard definition (SDTV) and high definition (HDTV) signal
formats and clock rates up to 1080p60 with support for
arbitrary display modes.
The GF9330 uses multi-directional adaptive filters for edge
processing, an adaptive vertical motion filter and an adaptive
inter-field motion filter. The GF9330 features detail
enhancement and noise reduction capabilities. The GF9330
also supports 3:2 pull-down, static/freeze-frame detection and
compensation and film rate conversions. The GF9330 may
operate as a stand-alone de-interlacer or may be used with
the GF9331 Motion Co-processor to enable higher quality HD/
SD de-interlacing with edge and vertical motion detection. The
two devices can be configured in tandem such that the
GF9331 sends edge detection and vertical motion filter control
information to the GF9330. These control signals adaptively
switch the GF9330's internal filters on a pixel-by-pixel basis.
The GF9330 integrates all required line delays and
seamlessly interfaces to off chip SDRAMs that form the
required field delays. The device may also operate in by-pass
mode should no processing of the input signal be desired.
