Serial data interface system and method using a selectively accessed tone pattern generator
First Claim
1. A system comprising:
- a tone pattern generator configured to generate a tone pattern signal customized for connectivity determination in accordance with a communications standard, wherein the tone pattern signal is generated to be within a predetermined frequency range supported by the communications standard for connectivity determination; and
a selecting system configured to selectively transmit the tone pattern signal or a data signal.

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.

11. A system compromising:
-
a tone pattern generating device configured to generate a tone pattern signal customized for connectivity determination in accordance with a communications standard, wherein the tone pattern signal is generated to be within a predetermined frequency range supported by the communications standard for connectivity determination; a first driver configured to; receive the tone pattern signal and a tone-on signal, and transmit the tone pattern signal based on an activation of the first driver; and a second driver configured to; receive a data signal and a diver control signal, and transmit the data signal based on an activation of the second driver. - View Dependent Claims (12, 13, 14, 15, 16, 17, 19)
