Cable Modem Termination S ystem (CMT S ) Bloc k Diagram
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 deploys in harsh environments.
