SINGLE-CHIP 2-LINE
BCM3341 FEATURES
• The BCM3341 broadband VoIP DSP solution provides
a seamless interface with Broadcom's PacketCable^TM
cable and DSL modem ICs, providing the industry
with the lowest cost, modular VoIP system solution.
• The BCM3341 integrates:
• High-performance 240-MIPS DSP and dual world
linecard programmable codec
• Internal memory supports G.711+ 1 complex vocoder (2
lines of either/or simultaneously)
• Supports all ITU G.7xx narrow-band vocoders, plus T.38
fax relay
• Complex vocoder, fax and modem relay memory
Expansion bus (128K×16) memory expansion (32K×16,
or 64K×16)
• World linecard support
• G.168 (2000) compliant echo canceler
• Extensive chip power management
• Integrated HVG circuit switch mode controller
Eliminates dual switching power controller for Low
Bat(–24V) and Hi Bat(–48V) power supplies
• Supports both narrow-band BroadVoice™16 and
wideband BroadVoice™32
• Integrated battery sensing
• Single 3.3V power supply
• 0 to 70ºC operation
