Frequently Asked Questions
What is the driver bit width of the DS92LX2121SQX/NOPB and how does it affect throughput?
The DS92LX2121SQX/NOPB features a 21-bit driver width, allowing it to serialize 21 parallel data bits into a single differential serial stream, significantly reducing the number of signal traces required on a PCB while maintaining high data rates suitable for video and industrial applications.
Which interface standard does the DS92LX2121SQX/NOPB use for control, and what does that mean for system integration?
This device uses the I2C interface standard for configuration, operating at standard I2C speeds. This allows a microcontroller to configure up to 128 devices on a 2-wire bus, simplifying PCB routing and reducing GPIO usage compared to parallel control schemes.
What package does the DS92LX2121SQX/NOPB come in, and how many pins does it have?
The DS92LX2121SQX/NOPB is housed in a 40-pin Quad Flat No-Lead (QFN) package with exposed thermal pad, conforming to JESD-30 code S-XQCC-N40, which offers a compact footprint of approximately 6×6 mm enabling dense PCB layouts in space-constrained industrial designs.
Is the DS92LX2121SQX/NOPB compliant with RoHS and halogen-free requirements?
Yes, the DS92LX2121SQX/NOPB carries a Pb-free code indicating RoHS compliance, and its JESD-609 code e3 confirms it meets halogen-free construction standards, making it suitable for environmentally regulated end products targeting markets requiring ≤900 ppm halogen content.
When would an engineer choose the DS92LX2121SQX/NOPB over a narrower 16-bit serializer?
Engineers choose the 21-bit DS92LX2121SQX/NOPB when the parallel data bus width exceeds 16 bits, such as in RGB666 plus control-signal video interfaces or wide sensor buses, avoiding the need for two narrower serializers and the associated 2× power, cost, and board-area overhead.
