    • High-speed differential serial interface (Maximum 2.7Gbps)
    • No need of lock condition signal or reset signal between transmitter and receiver. (Only differential signals)
    • Low EMI transmission by original DC balance protocol and scrambling.
    • Selectable 2 modes of CMOS parallel output current. (Receiver Mode)
    • The internal filter reduces an image disturbance. This is effective for the external noise that affects differential wire.
