BCM3034

Presents a high-performance, integrated solution for modulators in

digital cable-TV head-end, Cable Modem Termination Systems

(CMTS), digital microwave radio, SMATV and MMDS applications.

An integrated solution that reduces board space and costs with:

• On-chip 64K static RAM to eliminate external RAM

• Integrated 10-bit DAC with power control

• Additional burst modulator for out-of-band signaling

• Small footprint to enable high-density equipment

Improves bandwidth efficiency through 512/1024-QAM modulation.

• Enables advanced digital services over narrow RF channels.

Supports North American, European and Asian modulator standards

enabling a single design for worldwide application.

Programmable analog IF outputs up to 100 MHz simplifies image

rejection filters.

Programmable high-granularity digital output options remove the

need for SAW filters in final RF stage while providing designers

multiple options in DAC selection.

Advanced functions deploy in harsh environments.

• Distributed CMTS in Hybrid Fiber Coaxial Fiber Node
