(Adds that White House has 15 days to respond)
Sept 1 (Reuters) - Lattice Semiconductor Corp will seek U.S. President Donald Trump's approval for its proposed $1.3 billion sale to China-backed Canyon Bridge Capital Partners, Lattice said on Friday, gambling that the former real estate dealmaker will approve the tie-up against the advice of U.S. national security officials.
It will be the first such deal to hit Trump's desk and only the fourth time in three decades that a deal was put in front of a president after the Committee on Foreign Investment in the United States recommended against it. CFIUS scrutinizes deals for potential national security threats.
The move, first reported by Reuters earlier on Friday, comes after Lattice and private equity fund Canyon Bridge, funded in part by Chinas central government, spent eight months trying unsuccessfully to persuade CFIUS to clear the acquisition.
The White House will have 15 days to review the deal and reach a decision. It did not immediately respond to a request for comment.
Lattice shares rose 1.4 percent to $5.73 on Friday, below the deal's $8.30 offer price.
If Trump approves the transaction, it would be unprecedented. U.S. presidents, who have the final authority on such investments, have sided with the committee to block the past three deals. As a result, most companies have been reluctant to ask a president to go against the consensus of the country's national security establishment.
Relations between the United States and China are strained by disagreements over trade and the containment of North Korea's nuclear ambitions.
Critics of the deal, including some U.S. lawmakers, worry the technology gained through the acquisition of Lattice could be used by China's military, but the companies have argued it poses no such risk.
"Lattice remains of the view that the proposed transaction does not raise any national security concerns that cannot be addressed by the comprehensive mitigation measures that Lattice and Canyon Bridge have proposed to implement," Lattice said in a filing with the U.S. Securities and Exchange Commission.
Canyon Bridge supports Lattice's decision and believes "President Trump will recognize the benefits this investment will provide - to keep and grow jobs in the U.S. as well as expand Lattices product portfolio," it said in an emailed statement.
Canyon Bridge has told CFIUS it will commit to almost doubling the number of Lattice's employees, according to people familiar with the matter who asked not to be identified because details of the regulatory process are confidential. Portland, Oregon-based Lattice reported 986 full-time employees worldwide at the end of December.
However, the commitment has not swayed CFIUS, which focuses on resolving national security issues that pertain to deals, the sources added.
The deal's problems underscore U.S. efforts to prevent the transfer of sensitive technology to China. Chinese suitors have faced intense regulatory scrutiny in their pursuit of U.S. chip makers, leading to some deals being quashed in recent years.
The latest 75-day CFIUS review of the Lattice deal, the third since it was announced in November, ended this week with the panel informing Canyon Bridge and Lattice it would recommend Trump block the acquisition if they take it to him for review.
U.S. regulatory scrutiny of the Lattice deal grew after Reuters reported in late November that Canyon Bridge, based in Palo Alto, California, was funded partly by cash coming from Chinas central government and had indirect links to its space program.
Lattice makes programmable chips known as field programmable gate arrays, which allow companies to put their own software on silicon chips for different uses. It does not sell chips to the U.S. military, but its two biggest rivals, Xilinx Inc and Intel Corp's Altera, make chips used in military technology.
Trump's approach to relations with China has been mixed. He has criticized Chinese trade practices but also wants Chinese help in curbing North Korea's nuclear ambitions.
In the most recent example of a direct rejection by a president of a CFIUS application, Barack Obama in December blocked China's Grand Chip Investment GmbH from acquiring German semiconductor equipment supplier Aixtron SE. Aixtron's technology is used to upgrade U.S. and foreign-owned Patriot missile defense systems.
Canyon Bridge, based in Palo Alto, California, is a private equity fund whose major investor is China Reform Holdings Corp, an entity that invests money from China's central government and it has indirect links to the country's space program.
OTHER DEALS AT STAKE
Canyon Bridge's ability to acquire other Western semiconductor companies could be diminished if the Lattice deal collapses. This is because most acquisition targets have U.S. operations, making them subject to a CFIUS review.
Canyon Bridge is currently working on a bid for British semiconductor company Imagination Technology Group Plc, the sources said. If Canyon Bridge clinches that deal, it would be subject to CFIUS review since Imagination Technologies acquired U.S. chip designer MIPS in 2013.
While Canyon Bridge could choose to divest MIPS, which accounts for a small fraction of Imagination Technologies' business, there is no certainty that would be enough to resolve all CFIUS issues, according to the sources.
Imagination Technologies did not immediately respond to a request for comment.
Chinese buyers are awaiting CFIUS approval on other technology deals, including Unic Capital Management's $580 million acquisition of U.S. semiconductor testing company Xcerra Corp.
Canyon Bridge's direct appeal to Trump may not change anything, according to some experts.
"I worry that the most likely outcome is that they go to the president, the president says no, and that means that other CFIUS deals continue in limbo," said Stewart Baker, a partner at law firm Steptoe and Johnson LLP who is not involved in the Lattice deal.
Reuters reported in July that CFIUS was objecting to more deals in 2017 than in previous years, indicating that the secretive committee is becoming more risk-averse under Trump.
