SANTA CLARA, Calif., November 13, 2003 - PMC Sierra TM, Inc. (NASDAQ: PMCS) today announced that the PM8358 QuadPHY 10GX SERDES transceiver is the first to meet the Open Base Station Architecture Initiative’s (OBSAI) Reference Point 3 (RP3) interface specification. OBSAI comprises over 50 industry leading telecommunications companies working together to define wireless base station specifications. The RP3 interface interchanges formatted air interface user data as well as fast control data between the baseband processors and the radio (RF) modules (see Figure 1 and 2). The QuadPHY 10GX, a 4 port bi-directional 1.2 to 3.2 Gbit/s serial transceiver, allows base station manufacturers to evolve to higher speed serial links required by higher density baseband and radio cards thereby reducing systems costs.
