Filed:

Jan 5, 2009

Appl. No.:

12/348572

Inventors:

Josephus A. E. P. van Engelen - Aliso Viejo CA, US
Michael A. Sosnoski - Anaheim CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

G06F 13/00
G06F 3/00
H04L 5/14

US Classification:

710 71, 710 52, 710105, 710106, 710302, 710306, 370276, 370525

Abstract:

A system and method performs speed and connection handshaking between Beta signal ports and/or Bilingual ports in a serial data interface system. A tone pattern generator (e. g. , a flip-flop) can be used to generate a tone pattern signal representing approximately 49 MHz to approximately 62 MHz. A selecting system (e. g. , a multiplexer, a digital multiplexer, or the like) selectively transmits either the tone pattern signal or a data input signal. These signals include a driver control signal. A serializer serializes either the tone pattern signal or the data input signal. A clock device (e. g. , a clock divider) drives the tone pattern generator and the serializer. A driver receives and differentially transmits, along a twister-wire pair, either the serialized tone pattern signal or the serialized data input signal.
