Innofidei Integrated CMMB Processor IF228


1.1 Overview
Innofidei Integrated CMMB Receiver IF228 (IF228 for short) is the second generation
of Innofidei’s highly integrated single-chip CMMB receiver for China Mobile
Multimedia Broadcast (CMMB) system with built-in MBBMS support. It
combines an RF U-band tuner, a demodulator, and a user authentication module
(UAM) into a single 5×5mm package. IF228 provides superior mobile performance
with very low power consumption. With its high level of integration,
IF228 saves PCB board space and enables system manufacturers to significantly
reduce the number of the discrete components used. IF228 is ideal for devices
such as mobile phones with TD-SCDMA and CMMB functions, data cards, PCI-E
module, and so on.
IF228 further optimizes the CMMB receiver architecture over its previous generation,
yielding a much compact footprint and better performance. Its 5×5mm
package, the smallest in the industry, reduces the overall BOM. The ultra-low
power consumption design and the efficient power management decreases
power consumption significantly.


1.2 IF228 Application
IF228 can be used in:
• Mobile multimedia terminals
• Cellular phones and PDAs
• Ultra mobile personal computers (UMPCs)
• Mobile Internet devices (MIDs)
• Notebook
• USB dongles


1.3 IF228 Key Features
• Compliant with CMMB standard GY/T 220.1-2006 and GY/T 220.2-2006
• Compliant with CMCC standard: Terminal Specification for Mobile Multimedia
Broadcast/Mobile TV Service
