Si4421 Universal ISM Band

Si4421

FSK Transceiver

PIN ASSIGNMENT

DESCRIPTION

Silicon Labs’ Si4421 is a single chip, low power, multi-channel FSK

transceiver designed for use in applications requiring FCC or ETSI

conformance for unlicensed use in the 433, 868 and 915 MHz bands.

The Si4421 transceiver is a part of Silicon Labs’ EZRadio product

line, which produces a flexible, low cost, and highly integrated solution

that does not require production alignments. The chip is a complete

analog RF and baseband transceiver including a multi-band PLL

synthesizer with PA, LNA, I/Q down converter mixers, baseband filters

and amplifiers, and an I/Q demodulator. All required RF functions are

integrated. Only an external crystal and bypass filtering are needed for

operation.

This document refers to Si4421-IC rev A1.

See www.silabs.com/integration for any applicable errata.

See back page for ordering information.

FEATURES

The Si4421 features a completely integrated PLL for easy RF design,

and its rapid settling time allows for fast frequency-hopping, bypassing

multipath fading and interference to achieve robust wireless links. The

PLL’s high resolution allows the usage of multiple channels in any of

the bands. The receiver baseband bandwidth (BW) is programmable to

accommodate various deviation, data rate and crystal tolerance

requirements. The transceiver employs the Zero-IF approach with I/Q

demodulation. Consequently, no external components (except crystal

and decoupling) are needed in most applications.

 Fully integrated (low BOM, easy design-in)

 No alignment required in production

 Fast-settling, programmable, high-resolution PLL synthesizer

 Fast frequency-hopping capability

 High bit rate (up to 115.2 kbps in digital mode and 256 kbps

in analog mode)

 Direct differential antenna input/output

 Integrated power amplifier

 Programmable TX frequency deviation (15 to 240 kHz)

 Programmable RX baseband bandwidth (67 to 400 kHz)

 Analog and digital RSSI outputs

 Automatic frequency control (AFC)

 Data quality detection (DQD)

 Internal data filtering and clock recovery

 RX synchron pattern recognition

 SPI compatible serial control interface

 Clock and reset signals for microcontroller

 16-bit RX Data FIFO

The Si4421 dramatically reduces the load on the microcontroller with

the integrated digital data processing features: data filtering, clock

recovery, data pattern recognition, integrated FIFO and TX data

of a low accuracy (low cost) crystal. To minimize the system cost, the

Si4421 can provide a clock signal for the microcontroller, avoiding the

need for two crystals.

For low power applications, the Si4421 supports low duty cycle

operation based on the internal wake-up timer.

 Two 8-bit TX data registers

 Low power duty cycle mode

 Standard 10 MHz crystal reference with on-chip tuning

 Wake-up timer
