Microtune's 3-in-1 Tuner Featured in DTV Converter Box Certified by NTIA

First Silicon TV Tuner Chip Deployed in NTIA-Certified Set-Top Targeted for U.S. Coupon-Eligible Converter Box Program

PLANO, Texas — Microtune®, Inc. (NASDAQ: TUNE) today announced that its 3-in-1 TV tuner was deployed in a digital television (DTV) converter set-top box approved by the National Telecommunications and Information Administration (NTIA) for the $1 billion coupon-eligible converter box program (CECB) targeted to American consumers.

The recently certified set-top box contained the MicroTuner™ MT2131, the company’s flagship high-performance, multi-standard miniature tuner chip. Certification is an essential step for customers in qualifying their digital-to-analog converter boxes for sale under the CECB initiative, and NTIA approval means that manufacturers can move their products into production for an early 2008 rollout.

“Microtune is the first silicon tuner company to have its product used in an NTIA-certified converter box,” said James A. Fontaine, President and CEO of Microtune. “Our MicroTuner™ MT2131 is engineered to be a superior tuner that enhances the consumer TV viewing experience.”

Microtune recently announced that it was making its test-verification facilities available to its converter box customers to confirm that their designs meet the tuner-related technical specifications dictated by the NTIA for the CECB program.
