FTTC User Framer

Motorola => Freescale 

Applications

The primary application of the MC92052 is to provide

TC-sublayer processing functions for a user device,

e.g., a set-top box, in an FTTC network. Figure 2 shows

the location of the user device within an FTTC network

using a passive network termination. Figure 3 shows a

generic user device architecture using the MC92052.

The MC92052 uses an external memory for convolu-

tional interleaving of the downstream data. If the inter-

leaving depth is very small or if interleaving is not used,

the external memory is not required.
