Ultra ATA is the next genera-
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.
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
The new connectors are
color coded to identify:
1. system board connector
2. primary or master hard
drive connector
3. slave drive connector
Standard Issues
The Ultra ATA cable per-
formance specification is
part of the Small Form
Factor Committee No. 8049.
