What are the key features of DS92LX2122SQX/NOPB?
- 10 MHz to 50 MHz DC-balanced Channel Link III serialization supporting pixel clock rates for WXGA and XGA flat-panel display interfaces over a single differential cable
- Bidirectional control channel with I2C interface enabling touchscreen, camera control, and EDID data return over the same high-speed link cable
- 48-pin QFN package with differential LVDS inputs and 3-state parallel outputs for compact, low-EMI flat-panel display controller board designs
What is DS92LX2122SQX/NOPB used for?
The DS92LX2122SQX/NOPB is used as the display-side deserializer in Channel Link III flat-panel display systems, receiving serialized LVDS video data transmitted over a single differential cable pair from an upstream serializer and reconstructing the parallel RGB pixel bus for the display panel. Its bidirectional control path, compliant with I2C at up to 400 kbps, enables backlight control, EDID readback, and touchscreen or camera data return over the same cable assembly. Industrial HMI panels, medical display monitors, and in-vehicle infotainment screens benefit from the reduced wiring complexity and EMI performance of this Channel Link III solution.

Frequently Asked Questions
What pixel clock frequency range does the DS92LX2122SQX/NOPB support and which display resolutions does that cover?
The DS92LX2122SQX/NOPB operates from 10 MHz to 50 MHz pixel clock, covering display resolutions from QVGA (320×240 at 60 Hz requires approximately 6 MHz) up to WXGA (1280×800 at 60 Hz requires approximately 71 MHz) for panels near the upper end of its range and XGA (1024×768 at 60 Hz, approximately 65 MHz) for single-link configurations, making it well matched to 7-inch to 10-inch industrial and automotive LCD panels.
What does the bidirectional control channel of the DS92LX2122SQX/NOPB enable and how is it accessed?
The bidirectional control channel uses an I2C-compatible interface operating at standard mode (100 kbps) or fast mode (400 kbps). This allows the host system to send configuration commands to display peripherals such as backlight LED drivers and touch controllers, and to receive EDID data from the panel's EEPROM over the same differential cable pair as the video data. This eliminates the need for separate control wiring between the host board and display module, simplifying cable harness design.
How does DC-balanced encoding in DS92LX2122SQX/NOPB improve signal integrity over long cable runs?
DC-balanced encoding ensures that the average DC level of the serial LVDS stream remains constant, preventing low-frequency drift and baseline wander on the differential pair over cable lengths of 1 m to 5 m. This is essential for display links that must meet EMC radiated emission limits, as DC imbalance can create a low-frequency spectral component that broad-band EMI filters cannot suppress. The Channel Link III standard's 8b/10b-like DC balance also enables AC coupling of the differential pair, allowing the cable to be capacitively isolated for additional system safety.
What package does the DS92LX2122SQX/NOPB use and what thermal considerations apply?
The DS92LX2122SQX/NOPB is housed in a 48-pin QFN (Quad Flat No-Lead) package with an exposed thermal pad on the bottom. The compact footprint—typically 7 mm × 7 mm for 48-pin QFN—requires a PCB thermal via array under the exposed pad to conduct heat to internal copper planes. At full 50 MHz operation, junction temperature must be kept below the device's maximum rating, necessitating proper via-in-pad thermal design or an external heatspreader in high-ambient-temperature enclosures.
Is DS92LX2122SQX/NOPB compatible with older Channel Link II serializers or does it require a Channel Link III pair?
The DS92LX2122SQX/NOPB is designed specifically for Channel Link III systems and must be paired with a compatible Channel Link III serializer such as DS92LX2111 on the transmitter side. Channel Link III introduces the bidirectional control channel and DC-balanced encoding not present in Channel Link II, so it is not backward-compatible with Channel Link II serializers. Designers migrating from Channel Link II to III must replace both the serializer and deserializer ICs and update the cable to support the bidirectional control return path.
