Overview

The IEC-4-AFE-X Version 3.2 is part of Infineon´s

chip set for a splitterless, FDD (non-overlapped)

ADSL over ISDN linecard based on GEMINAX MAX

according to Ref [3.], chapter 4.2.2 of Ref [5.],

P-PM-QMFPQ-6F4P-1-,6-24,--93, H-8S

Annex B of Ref [6.] / Ref [7.], and Ref [8.].

Figure 1 shows the basic architecture of an integrated ISDN and ADSL linecard based

on GEMINAX MAX chip set. The IEC-4-AFE-X Version 3.2 is designed for use in central

office, DLCs and DSLAMs.

Features of the IEC-4-AFE-X Version 3.2

• Four port ISDN Echo Cancellation Circuit Analog Frontend

• Offers all features of AFE V2.1 (Ref [1.])1)

• Integrated digital transmit low-pass filter, which obsoletes the need for an discrete,

passive splitter device

• Conforms in connection with GEMINAX MAX chip set to Ref [3.], especially to the

following ISDN PSD masks:

- ’PSD mask for a 4B3T ISDN system with integrated splitter’ acc. to Ref [3.]

(4B3T ADSL friendly, compatible to ADSL US spectrum down to 138 kHz)

- ’PSD mask for a 2B1Q ISDN system with integrated splitter’ acc. to Ref [3.]

(2B1Q ADSL friendly, compatible to ADSL US spectrum down to 120 kHz)

• Footprint compatible to AFE V2.1 (Ref [1.])

• Serial control interface for communication with GEMINAX MAX chip set

1) With the exception of features for ISDN only, which are overruled by Ref [3.]
