SATA冗長アプリケーションに最適なマルチプレクサ/バッファ
SUNNYVALE, CA-March 3, 2003-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX3786, a serial-ATA compatible, 1.5Gbps multiplexer/buffer IC. Capable of switching a single serial data signal between two redundant I/O channels, this device is the only IC optimized for SATA redundancy applications such as switching signals between redundant disk controllers and the SATA disk.
SATA-type out-of-band signaling is supported using loss-of-signal detect on all three inputs and shutdown on the corresponding outputs. Receive equalization and transmit preemphasis are provided on the dual I/O channels to mitigate the effects of intersymbol interference in the signal path, providing residual jitter performance of less than 60psP-P for a 20" FR-4 path. Loopback can be enabled on the nonselected I/O channel.
The MAX3786 operates from a single +3.3V supply and typically consumes 520mW of power with preemphasis and equalization enabled. Available in a 5mm x 5mm 32-pin QFN exposed-pad package, the MAX3786 operates over a 0°C to +85°C temperature range. Prices start at $6.49 (1000-up, FOB USA).
