Yankton, S.D. MtronPTI offers a family of low voltage, surface-mount temperature compensated crystal oscillators (TCXOs) and VCTCXOs (voltage controlled TCXOs) with tight stability and excellent aging characteristics for network and wireless engineers.
The M6001/M6002 (3.3 V and 5 V TCXO) and M6003/M6004 (3.3 V and 5 V VCTCXO) series devices use hermetically sealed crystals, along with a low-aging process, to achieve consistent, long-term stability and minimal frequency shift after reflow. With this process, said the company, a first year aging rate of less than 1 ppm is achievable. A stability of ±0.5 ppm over an operating temperature range of 0°C to 70°C is available. Stabilities ranging from ±1 ppm to ±4.6 ppm over the temperature range of -40°C to 85°C are also offered.
A special version (L-stability option) of the M6001-6004 series is available for Stratum 3 applications. The company's unique approach to crystal compensation enables these devices to achieve Stratum 3 stability (±4.6 ppm) from -40°C to 85°C. In addition, the low phase noise (-143 dBc/Hz at 10 kHz) makes the M6001-6004 devices suitable for design engineers working on high data rate, low BER data communication network products. These devices are available with or without a tristate feature.
The HCMOS compatible M6001-M6004 series draws as little as 4 mA with a 3.3-volt supply at 19.440 MHz. This low-power consumption provides an advantage over similarly-specified ovenized oscillators for power-sensitive applications, said the company.
The M6003-6004 series is said to offer ±10 ppm minimum pull range with excellent tuning linearity performance for PPL applications. These products are available in frequencies from 5 to 30 MHz, and can be offered in a surface-mount FR-4 based platform with an industry standard 9 x 14 mm-footprint. Contact the factory for a 14-pin DIP configuration.
These M6001-M6004 series may be used in a wide range of applications including point to point/multi-point radios, WDM systems, Gigabit Ethernet, 10G and 40G systems, test and measurement, frequency synthesis, frequency translation, specialized mobile radio, WLAN as well as SONET, SDH, SERDES, and PCS base stations.
Pricing for the M6001-M6004 series is $35 each in quantities of 100. Delivery is eight to ten weeks.
