General Descriptions

The PT8R2401 is well suited to applications that fall

within the 2.4 GHz radio spectrum designated as

Industrial, Scientific and Medical (ISM).

Transmission scheme TDD – time division duplex.

Spreading type FHSS – frequency hopping spread

spectrum. Number of channels 79. Channel intervals 1

MHz [(f = 2.402 + k) GHz, k = 0,1,2,…78]. Hop rate

1.6k hops/second. Modulation Method GFSK 0.5BT

Gaussian. Support point-to-multipoint functionality.

The PT8R2401 control interface consists of a data

interface and a control interface for transmitting and

receiving data, and a serial interface for programming

the internal registers of the PT8R2401.

There are two subsections of the interface:

RF data and control path

Register control interface (serial).

Six signals are used in the RF data and control path

(TXDATA, RXDATA, TXACTIVE, RXACTIVE,

TXDATA_EN, SYNCDETECT). Four in the serial

register control interface ( TDI, TDO, TMS, TCK), one

system clock (DATACLK) and one reset signal (RET).

All of the signals are unidirectional.

Standard PT8R2401 has built-in antenna. Option

PT8R2401N has no built-in antenna. Customer can use

external antenna.

These modules can be integrated into almost any radio

electrical device for wireless data communications,

including PDAs, mobile phones, laptop computers, and

game pad devices.
