tion IDE (Integrated Drive
Electronics) bus. The current
IDE bus has a maximum
data transfer rate of about
16.5 MB/second. As the bus
speeds and disk drive per-
formances increase, the
cable assembly between
the motherboard and hard
drive becomes a limiting
factor in data transfer from
the drive.

Standard Issues
The Ultra ATA cable per-
formance specification is
part of the Small Form
Factor Committee No. 8049.
Compaq Computer and
Western Digital are the
major sponsors of the
standard.
The Ultra ATA connector
and cable assembly from
TE provide the customer
with improved electrical
performance by creating a
1:1 signal-to-ground ratio.
The connector design incor-
porates an IDC bus bar to
common the 40 additional
ground signals. The cable is
.025" centerline PVC ribbon
cable. The connector is fully
backward compatible with
existing 40-position headers
with pin 20 removed on
motherboards and disk
drives.
