54F/74F402 Serial Data Polynomial

Generator/Checker

General Description

Features

Guaranteed 30 MHz data rate

Six selectable polynomials

Other polynomials available

Separate preset and clear controls

Expandable

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-

Automatic right justification

Error output open collector

Typical applications:

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

Floppy and other disk storage systems

Digital cassette and cartridge systems

Data communication systems

’F402 is compatible with FAST devices and with all TTL

families.
