New Crystal & Oscillator Timing Support For TI 1394b Firewire® From Crystek Crystals

Fort Myers, FL, September 2003 - Crystek Crystals Corporation is now producing several new timing and frequency control products to support Texas Instruments' 1394b (FireWire®) devices. As previously announced, TI's 1394b (FireWire®) product, the TSB41BA3, is the first such device available for home networking of consumer, computing and audio/video (ANV) equipment.

A variety of Crystek crystals and oscillators at a frequency of 49.152 MHz meet the specifications Texas Instruments requires for use with the TSB41BA3 Chipset that is geared toward Long Haul or Long Range applications. The crystal is a fundamental 49.152MHz 5x7mm SMD, and the oscillator is a 49.152MHz, 1.8V, 5x7mm SMD.

All of the Crystek products are offered in a 5x7mm SMD package specified for 0°C/+70°C, -40°C/+85°C and -55°C/+125°C operating temp. range depending on application.

For the new 1394b FireWire® 800, TI offers the TSB81BA3 Chipset that is geared for Long Haul and High Speeds. Crystek recently has been tested by TI on a 98.304MHz 1.8V Oscillator required for this Chipset with Critical Start-up feature packaged in a standard 5x7mm SMD package specified for 0°C/+70°C and -40°C/+85°C operating temp. range.

The availability of IEEE 1394b devices enables much greater distances and higher performance for home networking and entertainment applications such as whole house, video and audio. The plug-and-play, quality of service and other ease-of-use features inherent to the 1394b FireWire® protocol provide consumers with a user-friendly home entertainment networking system. Crystek will continue to provide frequency controlled products to be used along with these devices from Texas Instruments.

Pricing for the 49.152MHz 5x7mm SMD crystal is $1.84 ea. in 10k-piece quantities; pricing for the 49.152MHz, 1.8V, 5x7mm SMD oscillator is $1.08 ea. in 10k-piece quantities; pricing for the 98.304MHz 1.8V, 5x7mm SMD oscillator is $2.57 ea. in 10k-piece quantities.
