The 20347-340E-12 from I-PEX is a 40-pin CABLINE-V series LVDS cable connector designed for high-speed differential signal transmission between PCBs and flat panel displays. The connector features an ultra-fine 0.4mm contact pitch in a right-angle SMD configuration, providing a low 1.0mm mated height ideal for slim consumer electronics and automotive display modules. The CABLINE-V architecture maintains 100 Ohm differential impedance across the connector interface, ensuring signal integrity for LVDS and high-speed serial protocols at data rates up to 8 Gbps per differential pair. The 40-pin configuration accommodates multiple LVDS data channels plus power and ground pins in a single compact connector. The right-angle orientation enables horizontal cable exit parallel to the PCB, making it suitable for thin-profile applications where vertical clearance is limited. The self-aligning structure ensures reliable mating even in high-vibration automotive environments.

The 20347-340E-12 CABLINE-V connector provides a controlled-impedance interface between a PCB and a flexible flat cable (FFC/FPC) carrying high-speed differential signals. The connector contacts are arranged in ground-signal-signal-ground (GSSG) quad groupings that maintain 100 Ohm differential impedance through the transition from PCB traces to cable conductors, minimizing reflections and signal degradation at the connector boundary. The right-angle SMD contacts are soldered to corresponding PCB pads, with the signal routing typically using microstrip or stripline transmission line geometries matched to the connector impedance. The FFC/FPC cable is inserted into the connector slot and secured by the actuator mechanism, which applies normal force to the contact interface for reliable electrical connection. The metal shield surrounding the connector body provides electromagnetic shielding that contains the differential fields within the connector and prevents external EMI from coupling into the high-speed signals. The 0.4mm pitch enables routing of 40 contacts in a compact footprint while maintaining crosstalk performance suitable for LVDS signaling.
