5. Multi-media processor MA55133
MA55133 is an LSI, which is designed on 3GPP 3G-324M Standard for a video telephone system.
Since protocol software is external,
MA55133 can run with another protocol like H.323 by changing its software.
Because of small power consumption - Typ.140mW and very small package - FPBGA, it is suitable to use
3G-324M LSI for portable apparatus.
Feature
- Based on 3GPP 3G-324M standard
- Video MPEG-4 (simple profile level1) or H263 (baseline)
- Audio AMR, G723.1, MP3 or AAC (program downloadable)
- Multiplexing H.223 (Level 0, 1, 2, processed by CPU with assistant hardware)
- Control H.245 (Processed all by CPU)
- Built-in 32bit RISC CPU(ARM7TDMI) for control, including H.245 and H.223
- Built-in 16bit DSP for audio CODEC
- Built-in SD card I/F
- Video input Rec601 YUV = 4:2:2, 8 bit I/F
- Video output Rec601 YUV = 4:2:2(8bit) / RGB 18bit
Built-in Picture-In-Picture Image Displaying Functions
Built-in On Screen Display(OSD) Functions
- Video CODEC 15fps for both encode and decode in QCIF size is possible.
- Program on SDRAM is executable without ROM (optional).
- Power supply VDDI=2.0V to 2.7V (internal), VDDO=2.7 to 3.6V (I/O)
6. Camera (OM6802)
The OM6802 is a highly integrated compact CMOS color camera module with embedded Camera Signal
Processor (CSP) that supports up to VGA resolution formats in a small package including a focused optical
system. It uses Philips See MOSTM technology for high sensitivity and low noise. The device is programmable
via an I2C serial interface. The
CIR656 compliant YUV output stream enables easy integration into mobile
phones or PDAs.
