Status
Active: In Production.
Description
The MAX3786 is an AC-coupled, serial-ATA (SATA)-compatible, 1.5Gbps multiplexer/buffer (mux/buffer) IC that provides the capability to switch a single serial data signal between two redundant I/O channels.
SATA out-of-band (OOB) signaling is supported using loss-of-signal (LOS) detect on all three inputs and
shutdown on the corresponding outputs. The high-speed inputs and outputs are all internally terminated, compatible with 100Ω differential systems, and must be AC-coupled to the controller IC and SATA-compatible disk drive.
Receive equalization (EQ) and transmit pre-emphasis (PE) are provided on the dual I/O channels to mitigate the effects of intersymbol interference in the signal path. Loopback can be enabled on the nonselected
I/O channel.
The MAX3786 operates from a single +3.3V supply and typically consumes 520mW with pre-emphasis and equalization enabled. It is available in a 5mm x 5mm, 32-lead thin QFN exposed-pad package and operates over a 0°C to +85°C temperature range.
