TMUX646ZECR

Analog Switches - Special Purpose Overview

The TMUX646ZECR is a 10-channel (5 differential) single-pole, double-throw bidirectional analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.5 V to 5.5 V and supports logic inputs compatible with 1.2 V and 1.8 V standards. The device provides a bandwidth of 6 GHz with a typical on-resistance of 6 Ω and ultra-low crosstalk of -40 dB at 1250 MHz. It features powered-off protection, maintaining high impedance when VDD is 0 V. The component is housed in a 36-pin nFBGA package (ZEC) measuring 2.45 mm × 2.45 mm.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix ZECR corresponds to the nFBGA-36 package and reel packaging configuration before procurement. Confirm that the 1.5 V to 5.5 V supply range aligns with the target system design requirements. Ensure compliance with RoHS directives as indicated in the manufacturer specifications. Check for any moisture sensitivity level requirements during storage and handling procedures.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring high-speed signal switching between multiple MIPI modules and a single processor port. The 6 GHz bandwidth and low skew characteristics make it suitable for demanding video and data interfaces. Consider the 1.2 V logic compatibility if interfacing with lower voltage processors without external translators. Evaluate the thermal resistance metrics for adequate heat dissipation in dense layouts.

Analog Switches - Special Purpose Part Context

The TMUX646 belongs to the TMUX646 series of optimized high-speed switches designed for MIPI compliant devices. It facilitates connecting multiple MIPI modules to a single CSI/DSI or C-PHY/D-PHY module. The device expands system capabilities by allowing a single MIPI port to interface with two distinct MIPI modules, addressing port limitations in compact electronics.

Analog Switches - Special Purpose Replacement Considerations

Consult the official datasheet orderable addendum for available package variations and potential cross-references. Verify functional equivalence regarding pinout, electrical characteristics, and package dimensions before substitution.

Analog Switches - Special Purpose FAQ

How does the TMUX646 handle powered-off conditions?

When VDD is 0 V, the I/Os and digital logic pins remain in a high-impedance state, preventing back-powering and maintaining isolation.

What logic levels are supported by the control inputs?

The SEL and OE pins support 1.2 V logic compatible inputs, eliminating the need for external voltage translators regardless of the VDD voltage.

Can clock and data lanes be interchanged?

Yes, the clock and data lanes can be interchanged to facilitate optimal layout for D-PHY and C-PHY applications.
