DVB-C/J83 demodulator
The CMS0022 Cable (QAM) Demodulator is fully compliant with the European, US and Japanese downlink cable Standards DVB-C EN 300 429 and ITU J83 Annexes A/B/C (including DOCSIS 1.1/2.0). The core provides all the necessary functions between modulated QAM input to transport stream output.
J.83B designs can operate either from internal memory (short interleaving modes) or from shared external memory (long interleaving modes) by means of a versatile access controller.
Typical applications of the CMS0022 include head-end video and broadband data transmissions systems (CMTS), cable modem test equipment and point-to-point (PTP) or point-to-multipoint microwave radio links.
A range of synthesis options allows the core to be tailored for any particular application.
