BC2102

Sub-1GHz RF Transmitter

Features

Development Tools

• Frequency bands: 315MHz, 433MHz, 868MHz,

915MHz

For rapid product development and to simplify device

parameter setting, Holtek has provided relevant

development tools which users can download from

the following link:

• Supports OOK/FSK modulation

• Supports 2-wire I²C interface

https://www.holtek.com/rf-workshop

• Operating voltage range of 2.2V~3.6V

• Programmable OOK symbol rate up to 25ksps

• Programmable FSK data rate up to 50kbps

• 0.4μA deep sleep mode current with data retention

• TX current consumption @ 433MHz:

General Description

The BC2102 is a low cost sub-GHz OOK/FSK

transmitter for wireless applications in the 315MHz,

433MHz, 470MHz, 868MHz and 915MHz frequency

bands. It is a highly integrated and low cost solution

for one-way transmitters. It only needs a crystal, a

few external capacitors and a few PA output matching

components on PCB to form a complete RF solution.

♦

17mA @ 10dBm POUT (FSK)

♦

11mA @ 10dBm POUT (OOK, 50% duty cycle)

• On-chip VCO and Fractional-N synthesizer with

integrated loop ﬁlter

The BC2102 consists of a highly integrated

fractional-N Synthesizer and a Class-E Power

Amplifier (PA). As it adopts a fractional-N

synthesizer, the users can potentially design their

transmitters to operate at a wider frequency range. A

class-E PA can deliver up to +13dBm output power.

With proper setting through an external MCU, the

BC2102 can support OOK and FSK modulation with

symbol rate of up to 25ksps and data rate of up to

50kbps, respectively.

• Supports low cost 16MHz crystal

• Supports hardware control mode – MCU is not

required for radio control

• Integrated 64×1-bit FUSE Data Memory

• Package type: 8-pin SOP-EP

Abbreviation Notes

TX: RF Transmitter

SX: Synthesizer

To minimize power consumption, the BC2102

provides a data tracking function. After no input data

is detected during a preset time which can be adjusted

through MCU, the BC2102 will return to the deep

sleep mode.

XO: External Crystal

PA: Power Ampliﬁer

OOK: On-Oﬀ Keying

FSK: Frequency Shift Keying

VCO: Voltage Control Oscillator

PLL: Phase Lock Loop

MMD: Multi-Mode Divider

XTAL: External Crystal

These features can be easily programmed through

I²C interface or internal FUSE. With these combined

features the BC2102 can provide a power-saving and

cost effective solution for a wide range of wireless

applications.
