CTA88

8 b it A d d r e s s - 8 b it D a t a e n c o d e r /d e c o d e r

CTA88 is an 8 bit address, 8 bit data encoder

and decoder combined in a single IC. This

device is intended to be used with ISM band

telemetry modules and can be operated in

either Encode or Decode mode.

CTA88 uses 1kbps differential Manchester bit

balancing with preamble and checksum. It

permits a simple, one way link to be

established, for simple remote control

applications, with a minimum of effort and

no customer software input.

CTA88 is

available in 28pin SO and DIL packages.

Features

•

Operating voltage (temperature):

4.0V-5.5V for standard version (-40°C to +125°C)

2.0V-5.5V for low voltage version (-40°C to +85°C)

Draws <2mA without external load

8 bit address and 8 bit data

256 different remotes with 8 controls each

Single packetised transmission for fast activation

Maximum usage of the range capability of an RF module

Adequate preamble to settle data slicer in the receiver.

Extra wake up preamble to allow for transmitter power up time requirements

Differential Manchester encoding of address, data and checksum

Synchronisation codes and checksum to reduce false triggering on noise

Suitable to be used with Narrow Band FM radio modules

Ceramic resonator or crystal oscillator up to 20MHz

Data rate up to 5.6kbps

•

Minimum external component requirement

Serial operation allow a PC to send or receive CTA88 command bursts

Decoder timeout

Up to 8 encoder/decoder modes including push button, delayed and continuous TX modes.

Applications

•

Security and Alarm systems

Emergency assistance call system

Status reporting and monitoring systems

RF Remote control systems

Industrial controls

HVAC controls

Simple On/Off switching

Long range telecontrol with Narrow Band FM radios
