DS92LV0422SQ/NOPB

Overview

The DS92LV0422SQ/NOPB is a deserializer from the Texas Instruments DS92LV042x series, designed to translate Channel Link LVDS video interfaces into high-speed serialized CML links. It accepts one CML input pair and outputs four LVDS data pairs plus one LVDS clock pair. The device supports parallel interface frequencies from 10 MHz to 75 MHz with a maximum serial data rate of 2.1 Gb/s. It operates on a 1.8 V logic supply (VDDn, VDDL, VDDP) and a 3.3 V I/O supply (VDDIO, VDDTX). The component is housed in a 48-pin WQFN package measuring 7.00 mm by 7.00 mm and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Fast random data locking capability that eliminates the need for external reference clocks or special synchronization patterns.
• Adjustable input receiver equalization to compensate for signal loss over long cables and backplanes.
• Integrated spread spectrum clock generation (SSCG) to minimize electromagnetic interference on the output parallel bus.
• Built-in at-speed link built-in self-test (BIST) mode for validating serial link integrity.

Applications

• Embedded video and display systems
• Medical imaging equipment
• Factory automation machinery
• Security and video surveillance cameras

Procurement Notes

Verify the specific suffix SQ indicates the RHS package variant when sourcing. Confirm the NOPB designation ensures compliance with RoHS standards and absence of lead-based materials. Cross-reference the manufacturer part number against official datasheets to ensure functional equivalence with existing designs.

Selection Notes

Select this component when upgrading from traditional single-ended wide buses to reduce trace count and FPGA I/O usage. Ensure the host system supports Channel Link LVDS parallel inputs. Verify that the application requires automatic data locking without external clock references. Check that the board layout accommodates the 48-pin WQFN footprint and thermal requirements.

Part Context

This device belongs to the DS92LV042x chipset family, which includes the DS92LV0421 serializer. Together, they form a complete serial link solution. The chipset allows seamless upgrades from popular Channel Link or OpenLDI LVDS devices. It reduces interconnect costs and simplifies design challenges associated with high-speed video transmission.

Replacement Considerations

The DS92LV0421 serializer can be used interchangeably with the DS92LV2421 or DS92LV2422. Designers may connect to host devices with different interface types, such as LVDS or LVCMOS, using these compatible parts.
