54F 74F402 Serial Data Polynomial Generator Checker

January 1995

54F 74F402 Serial Data Polynomial

Generator Checker

General Description

The ’F402 expandable Serial Data Polynomial generator

checker is an expandable version of the ’F401 It provides

an advanced tool for the implementation of the most widely

used error detection scheme in serial digital handling sys-

tems A 4-bit control input selects one-of-six generator poly-

nomials The list of polynomials includes CRC-16 CRC-

CCITT and Ethernet as well as three other standard poly-

nomials (56

order 48

order 32

order) Individual clear

and preset inputs are provided for floppy disk and other

applications The Error output indicates whether or not a

transmission error has occurred The CWG Control input

inhibits feedback during check word transmission The

’F402 is compatible with FAST devices and with all TTL

families

Features

Guaranteed 30 MHz data rate

Six selectable polynomials

Other polynomials available

Separate preset and clear controls

Expandable

Automatic right justification

Error output open collector

Typical applications

Floppy and other disk storage systems

Digital cassette and cartridge systems

Data communication systems
