PT4302是專為低功耗及高接收感度無線傳輸控制需求所開發的芯片.
高整合度的設計,使得PT4302僅需少數幾個被動組件配合即可工作,能減少電路板使用面積并縮短開發或樣機制作的時間.
PT4302在設計上特別對功耗作了有效管控,在5V時,315MHz的操作電流少于3mA ,對于日益嚴格的環保需求或手持式產品提供了良好的解決方案.
PT4302內建高性能的低噪聲放大器(LNA),整合壓控震蕩器(VCO)和回路濾波器(Loop Filter)的鎖相環(PLL)及使用10.7MHz作為其中頻,.
PT4302除省電省零件外,亦具有優異的接收感度和抗噪聲能力.特別適合用于汽機車防盜,遙控卷門、燈具、窗簾等環境噪聲較大的應用.
PT4302內建穩壓器,可操作在2.4V~5.5V.包裝型式則采用好加工的SSOP16小包裝。
PT4302+PT4450目前是行業的選擇的黃金擔當配合!

DESCRIPTION
The PT4302 is an ultra-low power OOK/ASK super heterodyne receiver for the 315/434 MHz frequency
bands. It offers a high level of integration and requires only few external components. The PT4302 consists of
a low-noise amplifier (LNA), a down-conversion mixer, an on-chip phase-locked loop (PLL) with integrated
voltage-controlled oscillator (VCO) and loop filter, an OOK/ASK demodulator, a data filter, a data slicing comparator and an on-chip regulator. The PT4302 is available in 16-pin SSOP package and
is specified over the extended temperature range (-40 to +85°C).
APPLICATIONS
• Automotive Remote Keyless Entry (RKE)
• Remote Control
• Garage door and gate openers
• Suitable for circuit applications that meet either the European ETSI-300-220 or the North American FCC (Part 15) regulatory standards
FEATURES
• Ultra-low power consumption: 2.7 mA for fully operation (315 MHz)
• Few external components
• Excellent Sensitivity of the order of –111 dBm(peak ASK signal level)
• Supply voltage range from 2.4 V to 5.5 V
• 250 MHz to 500 MHz frequency range
• Data rate up to 10 Kb/s
