5.GM1601/GM1501
The gm1601H is a dual channel graphics and video processing IC for Liquid Crystal Display (LCD)
monitors and televisions incorporating Picture in Picture, up to WUXGA output resolutions. The
gm1601H provides all key IC functions required for image capture, processing and display timing
control. On-chip functions include a high-speed triple-ADC and PLL, Ultra-Reliable DVI® receiver,
high quality zoom and shrink scaling engines, Motion Adaptive De-Interlacing (MADI), Low Angle
Diagonal Interpolation (LADI), an on-screen display (OSD) controller, a 100MHz on-chip X186
micro-controller (OCM), and a selectable double wide TTL or dual channel LVDS transmitter for
interface to displays. With all these functions integrated onto a single device, the gm1601H
eliminates the need for several system components, simplifying the design and reducing the cost of
high-end multimedia LCD monitors and televisions while maintaining a high degree of flexibility and
quality. The gm1601H is available in two silicon revisions – “BD” and “CF”. GM1601H-CF is a
backwards-compatible addition that incorporates some functional and quality improvements.

GM1601H Systtem Desiign Examplle
Figure 2 below shows a typical high-resolution multi-media LCD monitor/TV system based on the
gm1601H. Designs based on the gm1601H have reduced system cost, simplified hardware and
firmware design and increased reliability because only a minimal number of components are
required in the system.
