DIO1647WL36

Overview

The DIO1647 is a 10-channel (5 differential pairs) single-pole double-throw MIPI switch designed for high-speed applications. It supports 4 data lanes and 1 clock pair, facilitating connections between multiple MIPI-compliant devices and CSI or DSI modules. The device operates with an input voltage range of 1.65V to 5.0V and handles input signals from 0V to 1.3V. Key electrical parameters include a differential bandwidth of 3.5GHz, typical on-resistance of 7.5Ω for HS MIPI and 8.4Ω for LP MIPI, and quiescent supply current of 25μA. It features low off-isolation (-25dB), crosstalk (-30dB), and on-capacitance (1.5pF). Operating temperature ranges from -40°C to 85°C in a 36-ball WLCSP package.

Procurement Notes

Verify the specific ordering suffix WL36 corresponds to the 36-ball WLCSP package with 0.4mm pitch and tape-and-reel quantity of 3000 units. Confirm RoHS compliance status and ensure the operating temperature range meets system requirements. Cross-reference pin assignments for SEL and /OE control logic before integration.

Selection Notes

Select this component when interfacing MIPI sources with dual display or camera sinks requiring differential signal routing. Ensure the application voltage stays within 1.65V to 5.0V. Consider the 3.5GHz bandwidth limit for signal rates. Verify thermal management for the WLCSP-36 package in dense layouts.

Part Context

The DIO1647 belongs to Dioo Microcircuits' portfolio of analog switches targeting mobile and portable electronics. It addresses the need for flexible signal routing in compact form factors where space-constrained designs require efficient multiplexing of high-speed differential interfaces without significant signal loss.

Replacement Considerations

Check datasheets for alternative MIPI switches offering similar channel counts and bandwidth. Verify pin compatibility if substituting directly. Compare on-resistance and capacitance values to ensure signal integrity is maintained in the target application.

FAQ

What is the maximum differential bandwidth of the DIO1647?

The DIO1647 provides a differential bandwidth of 3.5GHz.

How does the SEL pin control the switching function?

When SEL is LOW, the common ports connect to the A-side paths. When SEL is HIGH, they connect to the B-side paths. If /OE is HIGH, all ports enter a high-impedance state.

What is the typical on-resistance for High-Speed MIPI mode?

The typical on-resistance for HS MIPI applications is 7.5Ω.
