Data Sheet
Device Overview
The IDT 89HP0604SB (P0604SB) 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 P0604SB, 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.
