Euroquartz宣布推出新型高频超低抖动振荡器
Euroquartz announces the launch of new high frequency ultra-low jitter Oscillators
Frequency control specialist, Euroquartz has announced the launch of two new ranges of oscillators. Offering ultra-low phase jitter of 150fs typical, the new oscillators are produced in the UK and are available in frequencies from 50 to 2100MHz with a choice of outputs including LVPECL, LVDS and CML differential. High current steering logic (HCSL) differential outputs are available for oscillators up to 700MHz
EQJF series oscillators feature a choice of supply voltages – 1.8, 2.5 or 3.3V – across the range apart from LVPECL with 2.5 and 3.3V only. Frequency stability specifications of ±25, ±50 and ±100ppm over both commercial (-10 to +70°C) and industrial (-40 to +85°C) temperature ranges are available as standard with tighter custom options supplied to special order.
Complementing the EQJF series is the EQVJF range of voltage controlled crystal oscillators (VCXOs) offering frequencies from 150 to 2100MHz (HCSL 150 to 700MHz) with identical options and similar RMS phase jitter performance.
Both ranges feature maximum ageing of ±3ppm in first year (±2ppm per year thereafter), duty cycle of 50%±5%, rise times of 0.35ns maximum (0.4ns for HCSL) and current consumption from 70 to 100mA typical depending on output logic selected. Additional features include start-up time of 5ms typical, 10ms maximum and output enable/disable functions.
RoHS compliant, the new EQJF oscillators and EQVJF VCXOs are housed in industry standard 8-pad, 7 x 5mm surface mount packages capable of withstanding 260°C for 10 seconds, twice.
Applications include flat panel displays for consumer TVs, video streaming systems via external cables (e.g. LDI), high speed serial communications links such as Serial ATA & FireWire, SONET, xDSL, SDH, set-top box and Ethernet cards.
Euroquartz宣布推出新型高频超低抖动振荡器
频率控制专家Euroquartz晶振公司宣布推出两个新系列的振荡器。这款新型振荡器在英国生产，具有150fs的超低相位抖动，频率范围为50至2100MHz，有LVPECL、LVDS和CML差分等多种输出可供选择。高电流导引逻辑(HCSL)差分输出可用于高达700MHz的振荡器
EQJF系列振荡器提供1.8、2.5或3.3V的电源电压选择，LVPECL只有2.5和3.3V。在商用(-10至+70°C)和工业(-40至+85°C)温度范围内，频率稳定性规格分别为25、50和100ppm，可根据特殊订单提供更严格的定制选项。
作为EQJF系列的补充，EQVJF系列压控晶体振荡器(VCXO晶振)提供150至2100MHz (HCSL 150至700MHz)的频率，具有相同的选项和相似的均方根相位抖动性能。
两个范围的第一年最大老化为3ppm(此后每年2ppm)，占空比为50%±5%，上升时间最大值为0.35ns为0.4ns)，典型功耗为70至100mA，具体取决于所选的输出逻辑。其它特性包括启动时间典型值为5毫秒，最大值为10毫秒，以及输出使能/禁用功能。
新款EQJF差分晶体振荡器和EQVJF VCXOs符合RoHS标准，采用工业标准8引脚、7x5mm表贴封装，能够承受260°C温度10秒钟，持续两次。
应用包括消费电视的平板显示器、通过外部电缆(如LDI)的视频流系统、高速串行通信链路，如串行ATA和FireWire、SONET、xDSL、SDH、机顶盒和以太网卡。
欧洲石英是一家总部位于英国的独立制造商，向全球电子制造业提供欧洲石英晶体、振荡器、滤波器和频率相关产品。该公司通过了AS9100认证，为包括主要原始设备制造商在内的广泛客户设计和制造全面的频率控制元件，涵盖军事和航空航天、通信、通用电子、计算、控制系统和石油化工等众多应用领域。
