描述 Description

STiD128 is STMicroelectronics’ next generation

front-end device for interactive cable gateway and

set-top box applications. STiD128 can also be

used standalone for cable modem application.

STiD128 provides a solution for operators to

specify a range of very high-performance

DOCSIS 3.0 STB, multimedia gateway or cable

modem platforms.

A total of 16 demodulation channels can be used

for DOCSIS out of which 8 channels can be used

as video channels. Allocation of the channels is

flexible.

A powerful dual core CPU allows telephony and

data distribution including routing/switching and

firewalling.
