BC2302A/BC2302B
Sub-1GHz Low-IF OOK RF Receiver
Features General Description • Frequency bands:
♦♦ BC2302A: 315MHz, 433MHz The BC2302x receiver devices adopt a fullyintegrated, 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-cost,
low power wireless applications. ♦♦ BC2302B: 315MHz, 433MHz,
868MHz, 915MHz • Operating voltage range: 2.5V~5.5V
• 0.5µA deep sleep current with data retention
• Low RX current:
♦♦ 3.2mA @ 433MHz
♦♦ 4.0mA @ 868MHz • Good reception sensitivity under 0.1% BER
♦♦ -112dBm at 10Ksps @ 433MHz
♦♦ The devices achieve -112dBm and -111dBm sensitivity
for the 433.92MHz and 868MHz bands, respectively.
They operate from a supply voltage of 2.5 to 5.5V and
typically require 3.2mA and 4.0mA at 433.92MHz …
