Rakon has released two crystals that offer a small footprint and low aging features into a single compact package. The RSX-5 crystal measures 5 × 3.2 × 1.1 mm and the RSX-6 crystal 4.9 × 3.1 × 0.75 mm. Rakon crystals also offer excellent shock and vibration performance.These compact crystals specialize in short-term stability of 1.0 ppb with a Root Allan Variance for 1 second Tau. They also provide frequency perturbations as low as 0.1ppm over -40 to 85 C. These crystals are suitable for application that are space constraints and require a low aging component. Typical applications include RF, wireless data and GPS.

TrueTime has introduced its new XLi time and frequency system that offers unprecedented flexibility, network monitoring and control, and redundancy in a precise time and frequency device. The system delivers extremely high precision outputs for a wide range of synchronization requirements demanded by government applications, including secure defense and intelligence communication systems, satellite ground stations, military test ranges and other critical government communication systems. Operating as a GPS timing receiver, the system can track up to 12 GPS satellites providing 1 × 10-12 frequency output accuracy and better than 30 ns accuracy. It can operate as either a GPS receiver or a Time Code Unit, can combine up to 10 plug-in option boards as well as oscillator upgrades and two power supplies for maximum versatility. The unit can provide, with options, an unprecedented array of outputs. Configuration recognition software automatically detects the unit's setup without modifications to the operating system to provide a “plug-and-play” configuration for current and future application needs. The list price for the basic XLi system is $3,300.

Analog Devices debuts the AD9858, DDS, with integrated 10-bit high-performance DAC, capable of operating at internal clock speeds of up to 1 Gs/s. It will generate a frequency-agile fundamental output frequency of up to 450 MHz (45 percent of internal clock rate) with a fine tuning resolution of 0.233 Hz (32-bit tuning word). device is a digitally-programmable, complete high-frequency hopping synthesizer. The frequency tuning and control words are loaded into the AD9858 via 8-bit parallel or serial loading formats. It contains an integrated programmable charge pump, 150 MHz phase frequency detector, and 2 GHz RF mixer. These fast-locking functional blocks can be combined in multiple configurations that provide high-performance frequency synthesis capability for a variety of applications such as frequency translation loops, tuners, etc. Temperature range is -40 to +85° C. Pricing in 1000 piece quantities is $44.50.

Lucix has announced three new clock references designed for use in fiber optic multiplexers and clock recovery circuits. These clocks, which operate at 9.95328 GHz (OC192), 19.9066 GHz, 39.8131 GHz (OC768) and at the corresponding FEC rates, offer low intrinsic jitter for these reference clock sources. The devices come in a variety of package configurations including stand alone, connectorized units (<0.25 in³ excluding connectors at 20 GHz), drop in units with stripline interfaces and carrier mounted devices suitable for integration into large assemblies. Surface mount packaging, compatible with high volume automated manufacturing, is available. They less than 1 MHz of frequency variation from -40 to +70° C at 10 GHz in a free running unit.

BVS re-introduces the Rhino II Rubidium-locked frequency source, a portable timing source designed for use where GPS reception may be poor or unavailable. All the outputs (eight unique 10 MHz sinewave outputs) are referenced by the Rubidium source. Rhino II contains an internal rubidium atomic clock with a stability of 1E^-11 and an accuracy of 1E^-12 with phase adjustable PPS aligning any of 512 CDMA base station offsets. Long-term stability and accuracy of the Rubidium clock are greatly (103) improved using GPS as a reference for periodic or permanent frequency adjustment. The Rhino II contains an internal power source allowing the user to maintain synchronization during transport of the unit. In addition, all functions are controllable via the front panel or RS-232 connection to a laptop PC (custom software included). Standards supported include CDMA, GSM, W-CDMA, 2.048 MHz, 10 MHz and 9.6 MHz.
