TCXO晶振在額定溫度范圍之外快速降低的巧妙方法

2022-04-28 16:30:11 

由于5G基礎(chǔ)設(shè)施部署在密度較大且控制較少的位置,因此在高溫和其他惡劣條件下的恢復(fù)能力在下一代通信系統(tǒng)中變得越來越重要.由于振蕩器在高溫下"保持涼爽",

Silicon Labs的定時技術(shù)可提供安裝在惡劣環(huán)境中的設(shè)備所需的穩(wěn)健性.

TCXO晶振和OCXO晶振用于需要高穩(wěn)定性頻率參考的蜂窩基站等應(yīng)用.由于可能存在冷卻系統(tǒng)故障,因此在此類事件中使用能夠承受高溫并保持系統(tǒng)功能的定時解決方案非常重要.除了持久的故障條件外,OCXO晶振和TCXO晶振的擴展溫度操作可以使系統(tǒng)更加強大和可靠,或根本不需要冷卻風(fēng)扇.

想象一下,在一個只有一個蜂窩塔的偏遠地區(qū),當無線基礎(chǔ)設(shè)施發(fā)生故障時需要撥打緊急電話!失敗可能是由同步和定時問題引起的,因為每個新一代無線通信的時序要求都會受到更大的壓力.

與主機系統(tǒng)中的電子組件相比,具有較低MTBF的這些冷卻風(fēng)扇仍然不是故障安全的并且可能由于多種原因而發(fā)生故障.由于存在這種風(fēng)險,因此了解關(guān)鍵組件(例如為系統(tǒng)提供心跳的振蕩器)在故障條件下的行為方式非常重要.

為此,我們推動了各種振蕩器的極限,測量超出額定工作范圍的穩(wěn)定性.我們測試了額定溫度為+85°C的溫補晶振器件并將其推至+125°C,并測試了額定溫度為+85°C,最高溫度為+105°C的OCXO.以下圖表顯示了在這些較高溫度下性能下降的結(jié)果.在每次測試中,我們將Silicon LabsMEMS振蕩器(用綠線表示)與來自不同供應(yīng)商的石英振蕩器進行比較,所有這些都在同一類別中且具有相同的溫度額定值.為了使比較更容易,每個器件的值在+85°C時從它們的頻率開始,從同一點開始.

當需要精確的穩(wěn)定性時-就像無線基礎(chǔ)設(shè)施設(shè)備一樣-設(shè)計人員經(jīng)常轉(zhuǎn)向溫補晶振和OCXO(烤箱控制振蕩器**).這些振蕩器設(shè)計用于在溫度變化時提供更好的頻率穩(wěn)定性.高溫和高溫變化是造成振蕩器不穩(wěn)定的主要原因.然而,TCXO晶振和OCXO晶振很難在額定工作溫度高于+85°C時找到,通常被認為是工業(yè)應(yīng)用的上限.

85°C可能看起來很高,但在當今更密集的操作環(huán)境中,系統(tǒng)機箱中的環(huán)境溫度會迅速升高.例如,電信和網(wǎng)絡(luò)設(shè)備在密集的熱環(huán)境中運行.這些系統(tǒng)中的許多系統(tǒng)使用主動冷卻-無刷直流風(fēng)扇,這是最常用的-將溫度保持在規(guī)定的工作范圍內(nèi).
