The new products reportedly feature: receive equalization (Rx EQ) and transmit pre-emphasis to improve signal integrity; impendent pre-emphasis control, allowing designers to tune outputs according to different trace or cable lengths; low power at 600mW; external control of Vbb; as well as low jitter performance (30 picoseconds) at 4.
