DM8148 operating frequencies of ARM, C674x, HDVICP2, HDVPSS, DDR

Hi all,

My application needs to support the following on DM8148:

1. Two channels (1080p30 + 360p30) H.264 encode simultaneously.
2. One Scaler (Down conversion)
3. One OSD (On Screen Display)
4. TCP/IP stack on ARM processor

DM8148 has multiple devices (part numbers), based on the frequencies of various peripherals. To select the appropriate DM8148 device I require the max operating frequencies of ARM, C674x, HDVICP2, HDVPSS, DDR.

To meet the above mentioned features, what frequencies should these peripherals (ARM,C674x, HDVICP2, HDVPSS, DDR) operate?

I just can’t select a high end DM8148 device, due to limited power budget.

Regards,
