In the race to provide design engineers with greater options at all frequency and voltage levels, SaRonix, Menlo Park, Calif., a manufacturer of frequency control products for 26 years, has introduced one of the industry's highest-frequency 3.3 Volt, voltage-controlled crystal oscillators (VCXO VCXO Voltage Controlled Crystal Oscillator ): the ST1317. Offered with its stable mate, the ST1307, this workhorse combination serves numerous applications between 32-125 MHz and 1-31.999 MHz respectively.

Harnessed into a space-saving 5.2 x 7.2 x 1.8 mm ceramic, surface mount package, SaRonix' ST1307/1317 VCXOs feature a frequency stability of (50 ppm over all operating conditions to meet the strict tolerances of Phase-Locked Loop (PLL PLL - phase-locked loop ) clock and data recovery circuits, frequency translation, and frequency synthesis needs in video compression, telephony and LAN/WAN LAN/WAN Local Area Network/Wide Area Network  communication environments.

"Given that network design engineers are looking for connectivity solutions at lower and lower voltages, we are especially pleased with the ST1317's applicability for ADSL See DSL.

 at 35.3218 MHz," noted Beat Kocher, manager of marketing and Business Development for SaRonix. "At the other end of the frequency spectrum, this same 3.3 Volt VCXO easily handles phase-locked loop applications right up to 125 MHz."

Available for 5 Volt operation at a maximum supply current of 30mA, SaRonix's ST1507 and ST1517 VCXOs offer the same high performance as the ST1307/1317 entry. All work within HCMOS HCMOS High-Density Complimentary Metal Oxide Semiconductor

In order to prevent an IP packet from propagating endlessly through the network, the value in the TTL field is reduced by each router.  logic circuits, and all offer tri-state output to simplify design, verification and testing.

Period jitter (RMS) is held at a maximum of 3.5 picoseconds for the ST1307/1507 and 20 picoseconds max for the ST1317/1517. The parts can be ordered for thermal operating ranges of 0 to +70( C or -40 to +85( C. Under a minimum input impedance of 50,000 ohms and a control voltage range of 0.5 to 4.5 or 0.3 to 3.0, pullability ranges of (32, (50, +/-80, or (100 ppm (APR APR

) can be specified.

Ideal for today's automated assembly environments, the leadless ceramic packages feature 6 gold-plated contact pads and are made available on 16mm tape in 500 piece reels. The ST1307/1317 and ST1507/1517 meet MIL-STD-202 for soldering heat, solvent and moisture resistance; and MIL-STD MIL-STD Military Standard  883 for mechanical and thermal shock, solderability, vibration, and terminal strength.

"The flexibility offered by this breed of low-voltage, high frequency VCXOs widens the field of available solutions for designer engineers," said Kocher. "The new ST1307/17 and ST1507/17 further SaRonix' goal to provide components that help our customers land in the 'winner's circle.'"
