日前，德州儀器 (TI) 宣布推出業界最小型 4 通道、低功耗、低抖動正弦至正弦波時鐘緩沖器。作為正弦波時鐘緩沖器系列產品中的首款產品，CDC3S04 可取代多達 3 顆具有相同頻率的獨立溫度補償晶體振蕩器 (TCXO)，從而可將板級空間與材料單 (BOM) 成本銳降近 50%。設計人員可將 CDC3S04 用于各種移動應用中，其中包括手機 (UMTS/WCDMA/GSM)、智能電話、移動因特網設備 (MID)、超移動 PC (UMPC)、導航設備以及全球定位系統 (GPS)。歡迎下載產品說明書或申請樣片：http://focus.ti.com.cn/cn/docs/prod/folders/print/cdc3s04.html 。

 

CDC3S04 的主要特性與優勢

· 1:4 低抖動、正弦至正弦時鐘緩沖器可取代多個 TCXO，從而可顯著節省板級空間與成本；

· 集成型片上 LDO 無需內部低壓降 (LDO) 穩壓器，可節省板級空間；

· 片上 LDO 可用作 TCXO 的電源開關，在低功耗待機時節省電源；

· 緩沖器可向 4 個不同的外設分配正弦波，而所增加的相位噪聲完全可以忽略，從而可最大限度地降低電磁干擾 (EMI)；
