Introduction
This data addendum along with the MARS2G5 P (TADM042G52) SONET/SDH 155/622/2488 Mbits/s Add/
Drop Interface Advance Data Sheet draft copy (DS02-015SONT) is the advance data sheet for the
TADMST622 V2.3 SONET/SDH interface device. The TADMST622 V2.3 provides a versatile solution for quad
STS-3/STS-1 and single STS-12/STM-4 linear and ring datacom/telecom applications.
Constructed using COM2 CMOS modular process, this device incorporates integrated SONET/SDH framing,
section/line/path termination, pointer processing, cross-connect functionality, and a powerful data engine. The
integrated circuit provides complete encapsulation and de-encapsulation for packet and ATM streams into and
out of SONET/SDH payloads.
Communication with the device is accomplished through a generic microprocessor interface. The device sup-
ports separate address and data buses.
Construction of different types of linear and ring STS-3/STS-12 (STM-1/STM-4) data equipment is simplified
and cost-efficient when using the TADMST622 device.
For the TADMST622 V2.3, all references to STS-48 mode in the MARS2G5 P (TADM042G52) data sheet
should be disregarded. In addition, the electrical characteristics and the reset default values of the registers
shown in the data sheet do not necessarily apply to the TADMST622 V2.3 792-pin package device.
Package Information
The TADMST622 V2.3 is available in a 792-pin PBGA package (TADMST622-BA23-DB). Refer to the
TADM042G52 advance data sheet draft copy (DS02-015SONT) for the package outline diagram.
TADMST622 V2.3 Limitations with Respect to TADM04622 V2.3
TADMST622 V2.3 is intended for use in quad OC-3 or single OC-12 TADM applications. It has the following
limitations with respect to TADM04622 V2.3:
■Only UTOPIA interfaces A and B are functional. Interfaces C and D are not functional.
■All 1.6 V core power supplies are now 1.5 V (1.425 V minimum, 1.5 V typical, 1.575 maximum).
Pin Information
Refer to the TADM042G52 advance data sheet draft copy (DS02-015SONT) for the pin descriptions.
