Programmable Crystal Oscillators Cut Package Size In Half Models in the the SG-8002JF series of plastic programmable crystal oscillators measure 5.1 by 7.1 mm, which is about half the size of current competing devices. They're mechanically and pad layout compatible with 5- by 7-mm industry-standard ceramic packages. Their reflowable, high-density mounting type J-lead SMD package provides mounting flexibility and effective cleaning, since it is mounted off the board. Also, these oscillators use phase-locked loop (PLL) technology and one-time PROM programmability for quick-turn custom conversion.Available frequencies range from 1 to 125 MHz. Two operating voltages, 3.3 and 5.0 V, are offered as well. Designers can select a TTL (5 V) or CMOS output level. The oscillators' stability is ±100 ppm over the −40°C to 85°C industrial temperature range. The devices can be programmed by any of the company's authorized distributors, which helps designers with short lead times and aggressive development schedules.
Pricing is approximately $1.54 each in 50,000-unit batches, depending on specifications.

Oscillator Line Expands While Cutting Turnaround Time Nine crystals and oscillators have been added to a line of distributor stocking standards. One addition, a set of 1.0-MHz oscillators, come in full- and half-sized metal DSP packages. The F4100 and F3345 5x7 ceramic oscillators, which target microprocessor and wireless product applications, now feature several additional standard frequencies. The 1.0-MHz DIP oscillator, meanwhile, can be fabricated in the company's Fast Fox unit for rapid turnaround time.Two series of programmable oscillators, the VCS25AXT VCXO and the FOX801BE TCXO, have been added as well. Also, the JITO-2 programmable oscillators come with standard or custom frequencies, from 340 KHz to 250 MHz, and ship within 10 working days. Prototypes and samples of the JITO-2 can be shipped within 48 hours. Changes in orders can be taken up to 10 days before shipping with no penalty, creating a JIT/BTO business model for advanced manufacturing centers.
Contact the company for pricing information. For example, the F3345 costs $3.50 in distributor quantities.

Crystal Quartz Resonator Operates In Bluetooth And Other Frequencies The CM4 series crystal quartz resonator is available in the 32.0-kHz Bluetooth frequency. Other versions range from 32 kHz to 1.0 MHz. The resonator is packaged in an SMD ceramic base with a metal lid. This microminiature, hermetically sealed package measures 5.0 by 1.9 by 0.8 mm, suiting the device for handheld wireless applications like cell phones and smart cards.Consuming just 1 µA, the CM4 has a ±30 ppm frequency tolerance. It also requires only a 1-µW drive level with ±3 ppm aging typical. The resonator feature high shock and vibration resistance, and its standard operating temperature ranges from −40°C to 85°C.
In 100,000-unit quantities, the 32-kHz tape and reel CM4 costs $1.66 each. Samples are available as well.
