• Two independent programming sets for scalar part, to define two 'ranges' per field or sequences over
frames
• Field wise switching between decoder part and expansion port (X-port) input
• Brightness, contrast and saturation controls for scaled outputs.
Vertical Blanking Interval (VBI) data decoder and slicer
• Versatile VBI-data decoder, slicer, clock regeneration and byte synchronization e.g. for World
Standard Teletext (WST), North-American Broadcast Text System (NABTS), close caption, Wide
Screen Signalling (WSS) etc.
Audio clock generation
• Generation of a field-locked audio master clock to support a constant number of audio clocks per
video field
• Generation of an audio serial and left/right (channel)
Digital I/O interfaces
• Real-time signal port (R port), inclusive continuous line-locked reference clock and real-time status
information supporting RTC level 3.1 (refer to document "RTC Functional Specification" for details)
• Bidirectional expansion port (X-port) with half duplex functionality (D1), 8-bit Y-C
– Output from decoder part, real-time and unscaled
– Input to scalar part, e.g. video from MPEG decoder (extension to 16-bit possible)
• Video image port (I-port) configurable for 8-bit data (extension to 16-bit possible) in master mode (own
clock), or slave mode (external clock), with auxiliary timing and handshake signals
• Discontinuous data streams supported
• 32-word ´ 4-byte FIFO register for video output data
• 28-word ´ 4-byte FIFO register for decoded VBI-data output
• Scaled 4 :2 :2, 4 :1 :1, 4 :2 :0, 4 :1 :0 Y-C
• Scaled 8-bit luminance only and raw CVBS data output
• Sliced, decoded VBI-data output.
Miscellaneous
• Power-on control
• 5 V tolerant digital inputs and I/O ports
• Software controlled power saving standby modes supported
• Programming via serial I 2 C-bus, full read back ability by an external controller, bit rate up to 400
kbits/s
• Boundary scan test circuit complies with the "IEEE Std. 1149.b1 - 1994"
• BGA156 package.
