Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix BBG corresponds to the 144-pin Plastic Ball Grid Array package as documented in official datasheets. Confirm current lifecycle status, as this component may be discontinued or subject to limited supply conditions. Ensure compatibility with existing 3.3V power supplies and industrial temperature range requirements before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for systems requiring high-density TDM switching with low latency or strict frame integrity. Evaluate the need for per-channel delay adjustment and automatic interface sensing. Consider the availability of the PBGA package and ensure the controlling microprocessor can interface with the 16-bit address and data buses efficiently.

Signal Switches, Multiplexers, Decoders FAQ

What are the two main operating modes of the IDT72V73260?

The two main operating modes are Processor Mode, where the microprocessor writes data directly to output channels, and Connection Mode, where data is switched from incoming serial streams based on pre-configured paths in the Connection Memory.

How does the device handle input frame skew?

The IDT72V73260 allows individual input streams to be offset from the frame pulse by up to +7.5 clock cycles using Frame Input Offset Registers, compensating for path delays in distributed switching systems.
