Description

PI3USB411 integrates two unique Pericom technology solutions into a single IC package. PI3USB411 offers the customer a solution that switches both high speed differential signals, with high bandwidth performance, as well as low THD audio signals. For handheld applications where both a USB data transfer port and a port for an external headset is required, the PI3USB411 solution can offer the ability to combine the two ports into one. With a single port, design engineers are faced with an issue of switching two completely different types of signals. One signal is a high speed differential signal, where bandwidth is the largest concern, and the second signal is an audio signal, where low THD is the largest concern. Pericom’s solution offers multiple channels within the PI3USB411 device. Two channels are targeted for high speed USB2.0 signals (Dx), and two channels are targeted for low THD audio signals (Ax). Due to its passive nature, all paths will allow bi-directional traffic.

Guaranteed by design. 2. The switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side. 3. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 4.

  • CL = Load capacitance: includes jig and probe capacitance.
  • RT = Termination resistance: should be equal to ZOUT of the Pulse Generator
  • Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
  • All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.
  • The outputs are measured one at a time with on transition per measurement.
