DS90UB948TNKDRQ1 - 1080p FPD-Link III Deserializer | Texas Instruments
MPN: DS90UB948TNKDRQ1 ✓ نشطDS90UB948TNKDRQ1 نظرة عامة
An FPD-Link III deserializer is a serializer-deserializer (SerDes) receiver IC that converts high-speed serialized LVDS-style differential streams into a parallel RGB/LVDS display interface, enabling long-reach video transmission over a minimal wire count while embedding a bidirectional control channel and DC-balanced data scrambling for EMI reduction. In the broader system taxonomy, this device sits inside interface ICs -> serializer/deserializer (SerDes) -> automotive video interface, sitting above physical-layer transceivers and below the display timing controller.
Key features include dual-port LVDS/OOpenLDI output, integrated adaptive receiver equalization supporting up to 10 m of coax or 15 m of STP cable at full speed, I2C-compatible control channel with up to 400 kHz pass-through, 9+ bidirectional GPIOs, hardware BIST (Built-In Self-Test), and an INT/AT power protection profile. The 64-pin WQFN package with exposed thermal pad provides low thermal resistance for automotive-grade operating temperature ranges. The device is suitable for ADAS surround-view, rear-view, and e-mirror camera systems that demand high-bandwidth uncompressed video over robust automotive cabling.
Typical applications include automotive 1080p camera deserialization for ADAS platforms, surround-view and rear-view camera hubs, digital instrument cluster displays, in-vehicle infotainment (IVI) head units, and LVDS-to-OOpenLDI bridge designs replacing legacy parallel RGB links. When designing, place 0.1 uF and 1 uF decoupling capacitors adjacent to each supply pin and route the FPD-Link III differential traces as a 100 ohm differential pair with controlled 50 ohm single-ended impedance for coax variants.

التطبيقات النموذجية
DS90UB948TNKDRQ1 مناسب لـ 6 التطبيقs: Automotive ADAS Front-View Camera Deserialization, Surround-View and Rear-View Camera Hub, Digital Instrument Cluster Display Receiver, In-Vehicle Infotainment (IVI) Head Unit, LVDS-to-OpenLDI Bridge for Legacy Display Replacement, Industrial HMI Panel Link Over Coax.
Automotive ADAS Front-View Camera Deserialization
The DS90UB948TNKDRQ1 deserializes one or two FPD-Link III streams from a paired DS90UB949A-Q1 or DS90UB949-Q1 serializer mounted on the camera PCB, delivering the recovered RGB or OpenLDI/LVDS video to an ADAS SoC or surround-view ECU. Its 3.36 Gbps per-lane data rate supports 1080p60 over a single coax or STP cable, while the AEC-Q100 qualification and -40C to +105C operating range ensure reliable operation in windshield-mounted front-view camera modules exposed to direct sunlight and thermal cycling. Designers typically run the upstream serializer at 1.8 V and route a single 50 ohm coax through the camera harness to the head unit.

Surround-View and Rear-View Camera Hub
In a surround-view ECU, the DS90UB948TNKDRQ1 aggregates video from four to six automotive cameras by demultiplexing dual FPD-Link III inputs across two OpenLDI/LVDS output ports, enabling stitching of four 1080p camera streams into a top-down bird's-eye view. The 3.36 Gbps per-lane bandwidth and adaptive equalization handle cable lengths up to 10 m of coax or 15 m of STP, which is essential for routing camera links through mirror mounts, tailgates, and bumpers in mass-market vehicles. The AEC-Q100 Grade 2 qualification matches automotive infotainment and ADAS safety integrity requirements.

Digital Instrument Cluster Display Receiver
The DS90UB948TNKDRQ1 functions as the deserializer endpoint in a digital instrument cluster, recovering LVDS/OpenLDI video and the bidirectional I2C back-channel from a DS90UB949A-Q1 serializer co-located with the head unit SoC. Its dual OpenLDI ports allow simultaneous driving of the cluster TFT and a secondary display from a single coax run, simplifying the wiring harness between the head unit and the steering-column-mounted cluster. The integrated GPIO and I2C pass-through also support touch, backlight, and panel enable/disable signalling without a dedicated microcontroller.

In-Vehicle Infotainment (IVI) Head Unit
The DS90UB948TNKDRQ1 is used in IVI head units that route HDMI or MIPI CSI-2 input through a DS90UB949A-Q1 serializer, then deserialize via this device back into an OpenLDI/LVDS stream for the central display. Its 3.36 Gbps per-lane throughput sustains 1080p60 graphics with low latency, while the bidirectional I2C control channel carries touch and backlight commands back to the SoC. AEC-Q100 qualification and -40C to +105C support ensure reliable dashboard operation under direct sun load.

LVDS-to-OpenLDI Bridge for Legacy Display Replacement
When replacing an aging parallel RGB/LVDS display panel with a modern OpenLDI TFT, the DS90UB948TNKDRQ1 acts as a bridge that converts FPD-Link III serial input from a DS90UB949A-Q1 serializer into a compliant OpenLDI output, allowing an automotive Tier-1 supplier to refresh the display without redesigning the head unit electronics. The same 64-pin WQFN package and pinout across production revisions supports second-source qualification, while the 3.36 Gbps per-lane bandwidth matches modern 1920x720 widescreen cluster resolutions.
موصى به
Industrial HMI Panel Link Over Coax
Beyond automotive, the DS90UB948TNKDRQ1 is deployed in factory-floor HMI panels where long-reach video, EMI immunity, and galvanic isolation through a single coax cable are required. With its adaptive equalizer supporting up to 10 m of coax at 3.36 Gbps, a panel mounted on a moving robotic arm can be driven by a remote industrial PC without EMI susceptibility on parallel LVDS cables. Although AEC-Q100 is automotive-grade, the same robustness is valued in industrial control cabinets with high motor/relay noise.

ملاحظات التصميم
Place a 0.1 uF and a 1 uF decoupling capacitor as close as possible to each 1.8 V supply pin (VDD18) of the DS90UB948TNKDRQ1, and a 10 uF bulk capacitor near the exposed thermal pad ground. The exposed pad (EP) must be soldered to a continuous ground plane to provide both the primary heat dissipation path and a low-inductance ground return for the high-speed FPD-Link III and LVDS signals.
Route FPD-Link III input pairs (RIN0+/-, RIN1+/-) and LVDS output pairs as 100 ohm differential microstrips or striplines with controlled 50 ohm single-ended impedance. Keep total skew within 5 ps between P and N traces and avoid right-angle bends; use gentle curves or 45-degree mitered bends. For coax variants, terminate the 50 ohm single-ended cable at the connector with a footprint that supports the FAKRA or HSD automotive coax standard.
Do not mix the DS90UB948TNKDRQ1 with non-automotive FPD-Link III deserializers (e.g., DS90UB928) on the same PCB unless you re-route the OpenLDI/LVDS pin mapping; the DS90UB948TNKDRQ1's dual-port OpenLDI output pinout differs from the DS90UB928's single LVDS output. Verify the serializer pairing (DS90UB949A-Q1, DS90UB949-Q1, or DS90UB947-Q1) per the TI compatibility matrix before committing to a layout.
