Russell Shaw from ZDNet IP Telephony blog points to IDC research on VOIP semiconductors. As the VoIP-specific semiconductor market grew over 40% in 2004, other vendors have been chipping away at Texas Instrument's (TI's) dominant share position. TI still held onto the #1 revenue share with its strong DSP offerings, especially in PBX and gateway sockets. Broadcom moved up to the #2 position, with high growth in its IP phone business. Mindspeed nabbed the #3 position, with rapid growth in media gateway silicon.
