DS26101  
8-Port TDM-to-ATM PHY  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
On the transmit side, the DS26101 receives ATM cells  
from an ATM device through a UTOPIA II interface,  
provides cell buffering (up to 4 cells), HEC generation  
and insertion, cell scrambling, and converts the data  
to a serial stream appropriate for interfacing to a  
T1/E1 framer or transceiver. On the receive side, the  
DS26101 receives a TDM stream from a T1/E1 framer  
or transceiver; searches for the cell alignment; verifies  
the HEC; provides cell filtering, descrambling, and cell  
buffering; and passes the cells to an ATM device  
through the UTOPIA II interface. Other low-level traffic  
management functions are selectable for the transmit  
and receive paths. The DS26101 can also be used in  
fractional T1/E1 applications.  
Cꢀ Supports 8 T1/E1 TDM Ports  
Cꢀ Supports Fractional T1/E1  
Cꢀ Compliant to ATM Forum Specifications for ATM  
Over T1 and E1  
Cꢀ Standard UTOPIA II Interface to the ATM Layer  
Cꢀ Configurable UTOPIA Address Range  
Cꢀ Configurable Tx FIFO Depth to 2, 3, or 4 Cells  
Cꢀ Optional Payload Scrambling in Transmit  
Direction and Descrambling in Receive Direction  
per ITU I.432  
Cꢀ Optional HEC Insertion in Transmit Direction with  
Programmable COSET Polynomial Addition  
Cꢀ HEC-Based Cell Delineation  
Cꢀ Single-Bit HEC Error Correction in the Receive  
Direction  
The DS26101 maps ATM cells to T1/E1 TDM frames  
as specified in ATM Forum Specifications af-phy-  
0016.000 and af-phy-0064.000. In the receive  
direction, the cell delineation mechanism used for  
finding ATM cell boundary within T1/E1 frame is  
performed as per ITU I.432. The DS26101 provides a  
mapping solution for up to 8 T1/E1 TDM ports. The  
terms physical layer (PHY) and line side are used  
synonymously in this document and refer to the  
device interfacing with the line side of the DS26101.  
The terms ATM layer and system side are used  
synonymously and refer to the DS26101’s UTOPIA II  
interface.
