LMH0070SQE

Serializers, Deserializers Overview

The LMH0070SQE/NOPB is a serializer manufactured by Texas Instruments, designed for serial digital video applications. It converts parallel LVDS inputs into a single high-speed serial output stream with a data rate of 3 Gb/s. The device operates on a single 3.3 V power supply within a voltage range of 3.135 V to 3.465 V. It features five differential LVDS inputs and one serial output. The component is housed in a WQFN-48 package suitable for surface mount installation. It supports an operating temperature range from -40°C to +85°C and has a typical power dissipation of 440 mW.

Serializers, Deserializers Procurement Notes

Verify the manufacturer designation as Texas Instruments, resulting from the acquisition of National Semiconductor's logic and interface portfolio. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the package matches the WQFN-48 specification and check moisture sensitivity levels for storage requirements before assembly.

Serializers, Deserializers Selection Notes

Select this component when a single-channel serializer is required for 3 Gb/s video interfaces. Compare input count against system needs, as this part provides five parallel inputs. Verify that the WQFN-48 footprint fits the PCB layout constraints. Ensure the 3.3 V supply rail aligns with the system power architecture.

Serializers, Deserializers Part Context

This device belongs to the LMH0070 series of serializers. It is functionally related to other components in the high-speed video interface family, such as deserializers and drivers. The part serves as a key element in converting parallel video data for long-distance transmission over coaxial cables.

Serializers, Deserializers Replacement Considerations

Check for direct pin-to-pin replacements within the LMH0070 series. Verify if alternative serializers from Texas Instruments offer compatible electrical characteristics and packaging for retrofitting.
