SATA/PCIe physical interface (MiPHY)

The MiPHY macrocell implements the lower (physical) layer protocols providing data

transmission and reception over a dual differential pair cable. The TX (transmit) and RX

(receive) serial channels operate plesiochronously (NRZ). The macrocell can be used in

Host or Device applications.

Main features:

●

Serial transceiver (PHYsical layer) serializer and deserializer

●

Direct support for 1.5/ 3.0 and 1.25/ 2.5/ 5.0 Gbit/s bit rates

●

20-bit parallel interface

●

Comma detect to provide word alignment of incoming serial stream

●

SSC modulation

●

Integrated impedance adaptation to transmission line characteristics

●

Out-of-band (OOB) signaling

●

Supported 1.2 V and 2.5 V power supply

●

High-performance PLL (input reference 100 MHz for PCIe and 100 or 25 MHz for

SATA)

●

Programmable TX buffer pre-emphasis, slew-rate and amplitude

●

Dedicated TX buffer regulator for:

–

Transmit buffer noise immunity

–

Buffer level stability
