BC2302C/BC2302D

Sub-1GHz Low-IF OOK RF Receiver

Features

General Description

• Frequency bands:

The BC2302x receiver devices adopt a fully-

integrated, low-IF OOK receiver with an automatic

gain control (AGC) function and a fully-integrated

OOK demodulator. The synthesizer is formed by an

integrated VCO and a fractional-N PLL to support

the 315, 433, 868, and 915MHz frequency bands. The

devices only require a crystal and a minimum number

of passive components to fully implement an OOK

receiver. With this high level of functional integration,

these devices provide excellent solutions for low

power wireless applications.

♦

BC2302C: 315MHz, 433MHz

♦

BC2302D: 315MHz, 433MHz, 868MHz,

915MHz

• Operating voltage range: 2.4V~5.5V

• 0.5µA deep sleep current with data retention

• Low RX current

♦

4.0mA @ 433MHz

♦

5.5mA @ 868MHz

• Good reception sensitivity under 0.1% BER

The devices achieve -108dBm and -107dBm sensitivity

for the 433.92MHz and 868MHz bands, respectively.

They operate from a supply voltage of 2.4 to 5.5V and

typically require 4.0mA and 5.5mA at 433.92MHz

♦

-108dBm at 10Ksps @ 433MHz

♦

-107dBm at 10Ksps @ 868MHz

• Wide RF input power range: from sensitivity to +10dBm

• Up to 40Ksps symbol rate

• Support 2-wire I²C interface for operation conﬁguration

• Support sniﬀ application for lower power application

• Package type: 8-pin SOP-EP

and 868MHz, respectively. An agile RSSI threshold

detection mechanism can further alleviate the impact

of interference on OOK reception. There are two

operation modes, one of which is the Auto RX mode.

By properly setting certain PCB wirings, they can

directly enter the RX mode. The devices also support

a sniﬀ RX mode, where the on/oﬀ RX mode function

can be controlled by an MCU to achieve a lower than

average power consumption using duty RX mode

operation.

Applications

• RF wireless ceiling lights/fans

• Keyless entry systems

The BC2302 series oﬀers two types of ICs. One is the

BC2302C which covers the 315 and 433MHz bands

while the BC2302D oﬀers a choice of four frequency

bands.

• Smart home appliances

• Door remote controllers

• Other wireless products
