Murata and Tokyo Denpa have jointly developed a hybrid crystal and ceramic resonator. The XRCGA series of Hybrid Crystal Resonators (HCRs) features a quartz crystal element manufactured by Tokyo Denpa alongside Murata's ceramic resonator technology in the same package. Murata's production technology results in smaller and lower cost devices that maintain the precision offered by the quartz crystal.

Ecliptek has announced the latest addition to its family of ceramic surface mount crystal clock oscillators. These new products complement Ecliptek’s extensive offering of quartz and MEMS based frequency control products.

IDT has announced the availability of the latest member of its FemtoClocks family – the FemtoClock Next Generation (NG). This new family of clock synthesisers features very low phase-noise performance and significantly improved power-supply noise rejection, allowing for increased bandwidth when used with serial interfaces.

ACAL has announced the availability of new sub-miniature surface-mount crystals which support the growing demand for stable and accurate RF clocking in portable or handheld wireless and other space-constrained applications.

Maxim has introduced the MAX9860, a low-power, mono audio codec with dual ADC paths and programmable digital voice filters. The device employs a flexible clocking scheme that utilizes common system-clock frequencies ranging from 10MHz to 60MHz, thereby eliminating the need for an external PLL and multiple crystal oscillators. The MAX9860 is ideal for voice headsets, digital cameras, cell phones, portable recorders, VoIP telephones, and conference...

Texas Instruments has introduced three new precision clock generators that have a crystal input, replacing up to four discrete high-frequency crystal oscillators with a single device. These devices provide a more cost-efficient solution that saves up to 50 percent more board space than competing solutions today. The CDCM61004 family improves system performance by achieving integrated RMS jitter of 500 fs, well suited for data communications equip...

Ecliptek Corporation has announced the increase of the available frequency range of its popular EC26 Series clock oscillators to a maximum of 200.000MHz. The EC26 (LVCMOS output) is available in a variety of configurations including frequency stability as low as ±20ppm maximum and an operating temperature range of -40°C to +85°C.

Maxim Integrated Products has introduced the DS4266, a 266MHz clock oscillator specifically designed for DDR memory applications. This device guarantees an extremely tight duty-cycle output of 48%/52%, and delivers RMS jitter of less than 1psRMS (12kHz to 20MHz) and cycle-to-cycle jitter of ±7.5ps (typ). It thus increases system-timing margins and enables an extremely low bit-error rate (BER) during data transfer at very high speeds. The DS4266'...

Precision Devices Inc (PDI) has introduced a new ultra miniature clock oscillator. The new OC2 clock oscillator has an operating frequency range of 1.544MHz to 80MHz and features a TTL/HCMOS output.

Ecliptek has announced that the frequency range for its line of high frequency LVDS and LVPECL ceramic surface mount 5mm x 7mm oscillators is being increased to 312.500MHz. The E13C7 / E15C7 (LVPECL output) and EL13C7 / EL15C7 (LVDS output) are available in a variety of configurations including frequency stability as low as ±20ppm maximum and an operating temperature range of -45°C to +85°C.
