WiBro 단말 Requirement • 기본 Requirement • 기존 유선 수준의 다양한 서비스를 제공하기 위해 기존의 이동통신단말에 비해 향상된 사양 필요 • High Quality Display • 고성능 CPU • 대용량 Memory • 단말 type 별 Requirement • WiBro 서비스에 따라 단말의 Requirement 세분화 • Information, Communication SVC • Wide LCD, QWERTY KBD, Camera 등 • Entertainment SVC • Wide LCD, Game Pad, T-DMB 기능 등 • Other Requirement • 무게, 확장 Memory, 외부 interface (CF, IrDA, Bluetooth, USB) 등

  9. 3. WiBro 단말 Architecture 1) WiBro DBDM 단말 Architecture 2) WiBro PDA 단말 Architecture 3) WiBro Laptop (PCMCIA) Architecture

  13. 4. WiBro 단말 Technical Issue 1) Chipset Size and Power consumption 2) Device Driver Porting 3) Interface between CDMA and WiBro chipset

  14. 16mm SoC 16mm 25mm Filter Amp RF diplexer S/W Filter 25mm BB TCXO This layout is just an example. WiBro 단말 Technical Issue • Chipset Size and Power consumption • SoC Type : Feb `06 • Reasonable Size : 16 x 16 mm2 • Power Consumption (TBD) : about Max 700 mw • All in one solution (RF + BB) • FPGA Type (Two Chip) : May `05 • Reasonable Size (Area) : 25 x 25 mm(RF + BB) • But Power Consumption : We won’t care of it at this chips

  15. WiBro 단말 Technical Issue • How will WiBro Module “Device Driver Porting” to “Rex OS ” in the MSM Chipset (CDMA/WiBro DBDM) • WiBro Module won’t depend on CDMA S/W Module • REX OS : Qualcomm’s CDMA S/W module • But can provide API and device driver for WiBro Module Frame Processing Applications REX WAP, WIPI, HTTP,FTP DHCP Client Session UI interface, sockets, … WiBro Extension Lower MAC Device Driver Interface Transport TCP/UDP Tx/Rx Buffer Mgmt Network IP EAP-MD5, -TLS, -TTLS, -LEAP Data Link RLP,PPP CS WiBro PHY Upper MAC Serial I/O API, … WiBro Module Driver RAM SoC Physical Host IO Host IO WiBro Module Qualcomm Software

  16. WiBro 단말 Technical Issue • Interface between “CDMA MSM Chipset ” and “WiBro BaseBand chipset” (CDMA/WiBro DBDM) i) The First Choice • Memory BUS Interface (DPRAM) ii) The Second Choice • SDIO Interface  flexible host bus interface (can be converted to SDIO using Glue Logic) TBD TBD 2.5 ~ 2.7 V MSM 65xx Wibro Chip 3.3 V TBD Rex_OS OS ? 1.375V  5% Analog voltage Analog voltage Digital Core voltage Digital Core voltage MSM65XX Chipset doesn’t support “Wait signal” 1.8 V  5% 2.7 V  5% 1.8 V  5% 2.7 V  5% Peripheral Voltage Peripheral Voltage MMC Interface I/F In case of SDIO Interface - 1bit transfer mode (SD/SDIO) - 4bit transfer mode (SD/SDIO) SD/SDIO 1bit and 4 bit interface

  17. 2.3G~2.4G Wibro ADC PHY/BB MAC/BB AFC RF DAC Memory (?) WiBro 단말 Technical Issue • Memory BUS Interface Core : 1.65V~1.95V Typ:1.8V I/O : 2.6V~2.8V Typ:2.7V Interface between MSM and Wibro BB ChipSet EBI2 - External Bus Interface 2 NAND (Flash) EBI2 MSM 8bit or 16bit interface EBI1 SDRAM We can use Dual Port RAM at this Interface I hope to use the same I/O voltage in your Wibro chipset

  18. WiBro 단말 Technical Issue • CF, PCI, SDIO interface We can also choice a CF or PCI Interface. But in this case, we have to make a Glue Logic for digital signal conversion. NAND 2.3G~2.4G EBI2 MSM ADC CF GLUE LOGIC PHY/BB MAC/BB PCI AFC RF SD I/F SDIO I/F DAC EBI1 MEMORY SDRAM MSM chipset internally has a SDIO Interface.(MSM6500 -> 1bit, MSM6550 -> 4 bit) therefore it will be one of the most simple connection between MSM and Wibro BB chipset.
