TNETC43x: DOCSIS* 2.0 Data

Cable Modem Reference Design



• Enables rapid time-to-market with a

complete hardware and software cable

modem reference platform

• Fully supports the DOCSIS* and Euro-

DOCSIS 2.0 standards

• Manufacturing flexibility choices including

four-layer (TNETC430) and two-layer

(TNETC436) lower-cost PCB

• Built with the same software architecture

as previous generations, ensuring stable,

robust, fast deployment

• Low-risk DOCSIS and Euro-DOCSIS

• Certification

• Enables rapid differentiated feature

development with modular software

drivers and application program

interfaces (APIs)

The TNETC43x cable modem reference designs provide cable modem developers with

quick time-to-market and a low-risk certication for DOCSIS* and Euro-DOCSIS 1.0/1.1/2.0

cable modems. This platform jumpstarts development efforts by providing a reference

board utilizing the TNETC460x integrated cable modem chip with proven DOCSIS and

Euro-DOCSIS software.

The TNETC43x designs were conceived with cost and robust design in mind. Based on

the integrated TNETC460x chip, these reference designs deliver a low-cost, low-risk

cable modem solution on a small circuit board footprint. Moreover, TNETC43x features

proven DOCSIS software, making it certication-ready.

The TNETC43x is a full-featured cable modem with 10/100 BaseT MAC/PHY and USB 1.1

interfaces, standby button and status LED indicators.

The TNETC460x is DOCSIS 2.0-compliant, and it supports high-speed data transfers up

to 38 Mbps downstream and 30 Mbps upstream.

The TNETC43x offers a convenient and trustworthy platform for the integration of compre-

hensive solutions for quick development of a cost-effective and differentiated cable modem.
