PAD DESCRIPTION

SYMBOL

Description

VCC

+5V supply

GND

Ground

VEE

-5V supply

RDP,RDN

output

Read Data, Differential read signal outputs

RWN

logic input

Read/Write : read = HIGH, write = LOW

WDP,WDN

input

Differential PECL or current mode write data input

FLT

output

input

In Write mode, a fault is flagged when FLT is high.

In Read Mode, a fault is flagged when FLT is low.

a 5k

Ω external resistor must be connected between FLT and VCC.

This pad is used as an input in MDS mode.

REXT

a 10k

Ω external resistor must be connected between REXT and GND

SEN

logic input

SCLK

logic input

Serial Clock line. 40 MHz max.

SDATA

logic

input/output

Serial Data line. Bi-directional interface

BFAST

logic input

Controls reader passband or enables the Imr generator depending on the state

of BFCTL bit from Reg.01

DRN

logic input

Selects the dummy head or performs a system reset depending on the state of

RSTDMY bit from Reg.09
