CONFIDENTIAL 3 Differences between the STi5512 and the STi5510
The new features of the STi5512 compared to the STi5510 are as follows.
• Software and pinout compatible with STi5510.
STi5512
• Genlock system can lock to an external analogue source and switch between STi5512 generated OSD and picture
in RGB.
• Digital YCrCb Output in 4:2:2 format to CCI.
• Support for 16 and 64 Mbit JEDEC or PC100 SDRAMs on the EMI.
• Support for boot bank width population options on customers boards (16 or 32 bit) by optionally applying address
shift based on bank width after reset.
• LMC (local memory interface) will support two 16 or one 64 Mbit JEDEC or PC100 SDRAMs with x16 bit
configuration. The ST20 system and the MPEG decoder and display are able to access all 64 Mbits of memory. The
caching of data in this area allows any of the 8 Mbytes of memory to be cached.
• Increased performance:
• 60 MHz CPU and system clock rate (also on STi5510)
• 72 Mbits/s transport stream input processing rate due to clock rate increase, with the restriction when
processing more than 11 matching scrambled sections per packet for more than 2 consecutive packets the
maximum data rate will drop to 60 Mbps.
• UART hardware RTS/CTS and ability to use FIFO’s in SmartCard mode (T=0 protocol) with auto-repeat transmit
of characters when NAKed from the SmartCard and precise record of characters in error which have been
NAKed automatically on receive.
• EMI supports SDRAM.
• External micro support using the ability to tristate all of the EMI data, address and strobe signals on a external DMA
request (MReq).
• DENC enhancements:
• Support for placement of teletext, WSS and VPS on any line.
• VBI insertion in square pixel mode.
• Two additional display modes for full resolution source video using Frame based filtering for Luma and Chroma
• Luma/chroma downsampling for 16:9 Letterbox display.
• Chroma upsampling for full resolution display.
