  CrystekCorporation推出了CVHD-957，這是一款具有待機模式的新型超低相位噪聲HCMOS壓控振蕩器(VCXO)，具有-90dBc的極低近端相位噪聲/Hz@10Hz偏移和-168dBc/Hz@100kHz偏移的典型本底噪聲。這種性能使Crystek的HCMOSVCXO系列成為行業(yè)領(lǐng)先的選擇，適用于以下應用：數(shù)字音頻廣播(DAB)、專業(yè)CD音頻設(shè)備以及數(shù)模轉(zhuǎn)換器(DAC)和模數(shù)轉(zhuǎn)換器(ADC))用于高清音頻。
  CrystekCVHD-957HCMOSVCXO還具有“待機功能”-當置于禁用模式時，內(nèi)部振蕩器完全關(guān)閉，其輸出緩沖器置于三態(tài)。該系列采用9x14mmSMT封裝，采用+3.3V電源供電，電流消耗為15mA。穩(wěn)定性為±100ppm。CVHD-957產(chǎn)生的頻率介于10MHz和50MHz之間。
  CrystekCVHD-957HCMOS時鐘振蕩器在美國制造，可從Crystek的庫存經(jīng)銷商處購買。http://www.gshqh.cn/

  Crystek的CVHD-957型HCMOSVCXO系列專為高清而設(shè)計音頻（高清音頻）。它具有-90dBc/Hz@10Hz偏移的典型低近端相位噪聲，本底噪聲為-168分貝/赫茲。憑借這種極低的相位噪聲性能，您將“聽到差異”。它還具有一個“待機功能”，即當置于禁用模式時，內(nèi)部振蕩器除此之外完全關(guān)閉到其輸出緩沖器被放置在三態(tài)。該系列采用9×14mmSMT封裝，采用+3.3V電源。數(shù)字音頻廣播(DAB)專業(yè),CD音響設(shè)備,用于高清音頻的DAC和ADC.溫度補償晶體振蕩器(TCXO)
  廣泛用于當今的無線通信系統(tǒng)。它們已成為手機和不斷發(fā)展的無線PDA行業(yè)的重要組成部分。高端TCXO也是電信等行業(yè)的重要組成部分。
  TCXO和簡單晶體振蕩器之間的主要區(qū)別在于，TCXO包含額外的電路，用于校正（補償）晶體的頻率與溫度特性。圖1描述了如何校正晶體的簡單說明。附加補償電路分為三大類：數(shù)字、模擬或模擬/數(shù)字組合。了解數(shù)字和模擬補償之間的差異很重要，因為它們在某些情況下是不可互換的。
  商品TCXO在-40ºC至+85ºC范圍內(nèi)提供+/-1.5ppm至+/-5ppm的頻率穩(wěn)定性，最標準的規(guī)格在-30ºC至+75ºC范圍內(nèi)為+/-2.5ppm。在0ºC至+70ºC范圍內(nèi)低于+/-1.5ppm的頻率穩(wěn)定性很難實現(xiàn)，因此屬于高性能類別。

  Crystek晶振振蕩器都是基于ASIC的，用于大批量制造。由于使用了特定的ASIC，晶體振蕩器公司無法提供任何定制，除了該系列范圍內(nèi)的頻率。此外，所有這些小型TCXO實際上都是VCTCXO——也就是說，它們提供了一個用于電氣調(diào)諧或偏差的引腳。
