ADN2913 - Continuous Rate 6.5 Mbps to 8.5 Gbps Clock and Data Recovery IC with Integrated Limiting Amp/EQ - 时钟和数据恢复/重定时 - 光学 - Analog Devices, LLC
The ADN2913 provides the receiver functions of quantization,signal level detection, and clock and data recovery for continuousdata rates from 6.5 Mbps to 8.5 Gbps. The ADN2913 automaticallylocks to all data rates without the need for an externalreference clock or programming. ADN2913 jitter performanceexceeds all jitter specifications required by SONET/SDH, includingjitter transfer, jitter generation, and jitter tolerance.
The ADN2913 provides manual or automatic slice adjust andmanual sample phase adjusts. Additionally, the user can select alimiting amplifier, equalizer, or 0 dB EQ at the input. The equalizeris adaptive or it can be manually set.
The receiver front-end loss of signal (LOS) detector circuitindicates when the input signal level falls below a userprogrammablethreshold. The LOS detection circuit has hysteresis to prevent chatter at the LOS output. In addition, the input signal strength can be read through the I2C registers.
The ADN2913 also supports pseudorandom binary sequence(PRBS) generation, bit error detection, and input data ratereadback features.
The ADN2913 is available in a compact 4 mm × 4 mm, 24-leadlead frame chip scale package (LFCSP). All ADN2913 specificationsare defined over the ambient temperature range of ?40°Cto +85°C, unless otherwise noted.
APPLICATIONS
FEC rates
ADN29xx（ADN2905、ADN2913、ADN2915和ADN2917）可提供下列接收器功能：量化、信号电平检测、时钟和数据恢复，适用于从6.5 Mbps到11.3 Gbps的连续信号数据速率。 ADN29xx自动锁定该数据信号，无需参考外部时钟或额外编程。 这些器件超过所有的SONET/SDH抖动要求，包括抖动传递、抖动产生和抖动容差。 所有规格均相对于-40°C至+85°C温度范围而言，除非另有说明。
为获得最佳的输入信号检测性能，ADN29xx输入电路可配置为限幅放大器、均衡器或0 dB均衡器。 此外，ADN29xx可以手动控制采样相位和限幅调整电平以优化输入数据眼部检测。
信号丢失(LOS)只能在限幅放大器输入模式下使用。 置位LOS表明输入信号电平已低于预设阈值。 LOS检测电路提供典型的6.0 dB迟滞特性以防LOS输出震颤。
置位失锁(LOL)表明输入信号速率偏移CDR VCO频率超过1000 ppm。
ADN29xx采用紧凑型4 mm x 4 mm、24引脚芯片级封装(LFCSP)。
该产品数据手册提供ADN2905/ADN2913/ADN2915/ADN2917的完整规格，使用评估板时应同时参考用户指南与数据手册。
ADN2905、ADN2913、ADN2915和ADN2917为引脚兼容的器件，具有相同的评估板。 每个EVALZ-ADN29xx评估板填充有不同的DUT： EVALZ-ADN2905上填充有ADN2905、EVALZ-ADN2913上填充有ADN2913、EVALZ-ADN2915上填充有ADN2915和EVALZ-ADN2917上填充有ADN2917。
