4.10 Flexible TTL Outputs (gmZAN3T Only)
The gmZAN3T builds in flexibility with the ability to:
• swap red and green channels,
• swap R, G, B most-significant-bit and least-significant-bit (reverse the bit-order of each R, G, B color
output).
• output single or double pixel width data in 24 or 48 bits.
This flexibility enables the building of cost effective (2-layer) PCBs.
4.11 Energy Spectrum Management (ESM)
High spikes in the EMI power spectrum may cause LCD monitor products to violate emissions standards.
The gmZAN3 has many features that can be used to reduce electromagnetic interference (EMI). These
include drive strength control and clock spectrum modulation. These features help to eliminate the costs
associated with EMI reducing components and shielding.
4.12 OSD
The gmZAN3 has a fully programmable, high-quality OSD controller. The OSD controller supports two
independent rectangles with graphics divided into “cells” that are programmable in size (from 8 x 8 to 18
x 18 pixels). The cells are stored in an on-chip static RAM and can be stored as 1-bit per pixel data or 2-
bit per pixel data. This permits a good compression ratio while allowing more than 16 colors in the image.
Some general features of the gmZAN3OSD controller include:
