462 AMD Geode™ LX Processors Data Book
Video Input Port
33234H
6.9 Video Input Port
6.9.1 Features
• VESA 1.1, 2.0 and BT.601, BT.656 compliant, 150 MHz
(excludes host interface).
— Standard 9 or 17 pin interface (8/16 data + clock)
— 8/16-bit BT.656 video
— TASK A/B video and VBI (two video streams)
— 8/16-bit ancillary data
— HD capable (up to 1280x720 progressive scan,
1920x1080 interlaced)
— VIP 1.1 compatible mode (8 bit)
• 8/16-bit BT.601 type input video with HSYNC and
VSYNC
• 8-bit message and streaming video transfer mode
— (8 + clock + control on vid[10:8])
• Video data stored in linear or planar buffers
• Even line or even field decimation (4:2:2 -> 4:2:0 transla-
tion)
• Automatic paging for multi-frame storage
• Provides full frame buffer generation from interlaced
input (Weave)
• Mutli-burst GLIU packets (programmable)
• Internal loopback using VOP outputs as source data
• vip_sync_to_pin output pin to request next frame or data
packet from external data source (GenLock)
• vip_sync_to_vg output to DC/VP for frame synchroniza-
tion (VSYNC indication)
• frame_to_vg output to DC/VP for frame synchronization
(odd/even field indication)
• vip_int output for interrupt generation on frame/field/line
boundaries
6.9.1.1 Performance Metrics
— System goals:
— 150 MHz video interface
— 400 MHz GLIU interface
— Adequate GLIU bandwidth in HD capture mode (HD
VIP requires ~20 million QWORDs/sec)
— GLIU Latency requirements
