PTC/普诚科技正在热卖PT4317(低功耗UHF OOK/ASK超外差接收器).
      PT4317为PT4316的改进版本.PT4316使用SAW resonator作为本振，只用少数外部电路来配合即可作为250MHz~500MHz的OOK/ASK接收端.为了强化接收性能,PT4317做了以下四点改善：缩小中频频宽到600KHz，这样大大增加抗干扰能力；降低SAW起振幅度,减少了本振泄漏，更容易通过安规测试;提升接收灵敏度；缩短启动时间,可以配合有快速启动客户的需要。
   采用SSOP-16封装。

    DESCRIPTION
The PT4317 is a low power consumption single chip OOK/ASK superheterodyne receiver for the 315 MHz and 434 MHz frequency bands and which offers a high level of integration and requires few external components. The PT4317 consists of a lownoise amplifier (LNA), mixer, SAWbased local oscillator, onchip gmC bandpass
filter, intermediate frequency (IF) limiting amplifier stage with receivedsignalstrength indicator (RSSI), and analog baseband data recovery circuitry (data filter, peak detector, and data slicer). The PT4317 is available in a 16pin SSOP package.

FEATURES
· Low current consumption (4.3 mA at VDD = 5.0 V)
· 2.4 V to 5.5 V supply voltage operation range
· Optimized for 315 MHz or 434 MHz ISM Band
· Sawbased oscillator with low frequency drift
· Onchip IF filter with better adjacent channel rejection capability
· Power down mode with very low supply current (<1 mA)
· Low external parts count
· 16pin SSOP package


APPLICATIONS
· Keyless entry systems
· Remote control systems
· Garage door openers
· Alarm systems
· Security systems
· Wireless sensors

    主要应用到：汽车摩托车防盗器、车库门、电动门窗、闸门、工业控制、遥控灯、遥控开关、通讯以及安防、物联网、智能家居等相关无线领域
