Device Overview
The IDT 89HP0604SB is a 6Gbps SAS/SATA
®
Repeater device featuring IDT EyeBoost
™
technology that
compensates for cable and board trace attenuations and ISI jitter, thereby extending connection reach. The
device is optimized for SAS/SATA high speed serial data streams and contains four data channels, each
able to process 6Gbps transmission rates. Each channel consists of an input equalizer and amplifier, signal
detection with glitch filter, as well as programmable output swing and de-emphasis. Allowing for application
specific optimization, the 89HP0604SB, with its configurable receiver and transmitter features, is ideal for
SAS/SATA applications using a wide combination of cables and board trace materials.
All modes of active data transfer are designed with minimized power consumption. In full shutdown mode,
the part consumes less than 40mW in worst case environmental conditions.
SAS/SATA Compliance
The device was designed to provide end users with features needed to comply with SAS/SATA system
application requirements:
– SAS/SATA Out-of-Band (OOB) Support
– Jitter, eye opening, and all other
Data path
AC and DC specifications.

89HP0604SB Block Diagram
The 89HP0604SB contains four
high speed channels as shown.
Each channel can be routed to
different outputs. Depending on
user configuration via mode
selections, input traffic can be
muxed or demuxed. Powerdown
(PDB) is provided for state and
channel control.
