PI6C49S1506FAIE

Clock Buffers, Drivers Overview

The PI6C49S1506FAIE is a high-performance differential fanout buffer supporting up to 1.5 GHz output frequency. It features six differential outputs organized into two banks, with user-configurable signaling standards (LVDS, LVPECL, or HCSL) per bank. The device integrates selectable reference inputs for single-ended, differential, or crystal sources and utilizes proprietary input detection to manage illegal conditions. Key electrical parameters include an ultra-low additive phase jitter of less than 0.03 ps typical at 156.25 MHz, propagation delay of 1.5 ns typical, and low skew under 40 ps within banks. It operates on separate 2.5 V or 3.3 V power supplies for core and output stages.

Clock Buffers, Drivers Feature Summary

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'E' indicates tape and reel packaging configuration. Confirm RoHS compliance status as specified in the datasheet. Ensure the TQFP-32 package dimensions align with PCB footprint requirements. Check for any specific environmental certifications required by the target application.

Clock Buffers, Drivers Selection Notes

Select this component when distributing low-jitter clocks to multiple destinations requiring mixed signaling standards. Choose based on the need for independent bank configuration of LVDS, LVPECL, or HCSL outputs. Consider the separate power supply requirement for level shifting if interfacing with different voltage domains.

Clock Buffers, Drivers FAQ

How are the output signaling standards configured?

The signaling standard for each bank (A and B) is configured via OPMODEA and OPMODEB input pins, allowing selection among LVPECL, LVDS, HCSL, or Hi-Z states.

What is the maximum output frequency supported?

The device supports a maximum clock output frequency of 1.5 GHz for LVPECL and LVDS outputs, and 250 MHz for HCSL outputs.

Can the device accept single-ended clock inputs?

Yes, the device can accept single-ended inputs by wiring the differential input pins appropriately, using a bias circuit to generate a reference voltage equal to VDD/2.
