A range of new crystals and crystal oscillators supports Texas Instruments' 1394b FireWire products, such as the TI TSB41BA3 device. The crystals and crystal oscillators have a fundamental frequency of 49.152 MHz and operate at 1.8 V. They come in surface-mount-device (SMD) packages measuring 5 by 7 mm, and are specified to operate over the temperature ranges of 0°C to 70°C, −40°C to 85°C, and −55°C to 125°C, depending on the application. Price for the crystal and the oscillator is $1.84 and $1.08 each, respectively, in 10,000-unit lots. Each 98.304-MHz, 1.8-V, 5- by 7-mm SMD oscillator (tested by TI) costs $2.57.
