SUB-1GHz ASK/OOK

Eastsoft RKE RX系列

HW3020/3022:

  • 一款工作在 270MHz~370MHz(主要應用在 315MHz)頻段。
HW3021/3023:
  • 一款工作在 370MHz~480MHz(主要應用在 433.92MHz)頻段,
  • 具有自動增益 控制、靜噪以及鏡像抑制功能的 ASK/OOK 超外差接收器芯片。
  • 芯片采用 SOP8 封裝,僅需要一個晶振和其它少量的外部元器件就可以工作,
  • 非常適合應用于低成本,低功耗的遙控門禁系統(RKE),胎壓監測系統(TPMS)和遠程操控等領域。
  • 在數據速率為 2kbps 時:
    HW3020/3022的接收靈敏度可以達到-115dBm。
    HW3021/3023接收靈敏度可以達到-114dBm(在誤包率 PER 為<1% 的條件下)。

    芯片最高支持 10kbps 的數據速率,支持的電源電壓范圍為 2.1V~5.5V,典型工作電流為3.9mA。

  • 在待機模式下,芯片的典型電源電流值可降至100nA 以下。
  • 芯片還具有靜噪功能,在檢測到有效比特之前,靜噪功能可以抑制數據輸出引腳的輸出。
  • 該芯片支持的溫度范圍為–40°C to +85°C。
  • 同時,該芯片可支持 >±4KV HBM ESD 和>±750V CDM ESD。 
  • 另外,該芯片還具有系統快速啟動功能(<2ms)。
