"Consumers and enterprises want access to high-speed video and data wherever they are, on whatever devices they are using," explained Tom Lynch, the Tyco Electronics CEO, in a statement. This extends from smartphones to HD and 3-D TVs to computers with advanced video-conferencing capabilities, he added.

The Swiss electronics firm, which was downgraded by Merrill/BofA on Monday, will buy ADC for $12.75 a share as part of the all-cash deal, which is expected to close in the fourth quarter of this year.

The transaction is structured as a tender offer, to be followed as soon as possible by a merger, said Tyco Electronics. The deal is expected to be accretive by approximately 14 cents per share in the first full year after closing, excluding any acquisition-related costs.

Tyco Electronics also announced preliminary third-quarter results on Tuesday, reporting revenue of $3.1 billion, a 23% increase on the same period last year. Excluding items, Tyco earned 70 cents a share. Analysts surveyed by Thomson Reuters had expected sales of $3.04 billion and earnings of 63 cents a share.
