PI6C49S1506FAIEX

Clock Buffers, Drivers Overview

The PI6C49S1506FAIEX is a high-performance differential fanout buffer from Diodes Incorporated, housed in a 32-pin TQFP package. It supports output frequencies up to 1.5 GHz with six differential outputs organized into two configurable banks. The device allows per-bank selection of LVPECL, LVDS, or HCSL signaling standards and accepts single-ended, differential, or crystal inputs. Key electrical parameters include a typical propagation delay of 1.5 ns, intra-bank skew under 40 ps, and ultra-low additive phase jitter below 0.03 ps (typical). It operates on separate VDD and VDDO supplies ranging from 2.375 V to 3.465 V within an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Six differential outputs divided into two banks with user-configurable signaling standards (LVPECL, LVDS, or HCSL) for each bank.
• Ultra-low additive phase jitter performance, typically less than 0.03 ps at 156.25 MHz.
• Supports selectable reference inputs including differential clocks, single-ended signals via biasing, and external crystals.
• Low output skew (<40 ps) within the same bank and low propagation delay (typ. 1.5 ns).

Clock Buffers, Drivers Applications

• Networking systems including switches and routers
• High-frequency backplane-based computing platforms
• Telecom infrastructure requiring low jitter clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'EX' corresponds to tape and reel packaging as indicated in the datasheet notes. Confirm that the specific revision matches the required electrical characteristics. Ensure supply voltage levels align with the selected output standard, as VDD and VDDO may require independent regulation for level shifting compatibility.

Clock Buffers, Drivers Selection Notes

Select this component when distributing high-speed differential clocks with mixed interface requirements across different system sections. The dual-bank architecture allows mixing LVPECL and LVDS outputs on the same device. Consider the separate power supply pins (VDD/VDDO) for noise isolation and ensure adequate decoupling capacitors are placed near the pins to maintain jitter performance.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49S1506 series of high-performance fanout buffers manufactured by Diodes Incorporated (formerly Pericom). The FAIE suffix indicates a lead-free, green RoHS-compliant device in a 32-pin TQFP package. The 'X' suffix denotes tape and reel packaging for automated assembly.

Clock Buffers, Drivers Replacement Considerations

Check pin-to-pin compatibility with existing designs if substituting other PI6C49 series devices. Verify that alternative buffers support the same configurable output standards and frequency range up to 1.5 GHz. Ensure thermal and mechanical dimensions match the TQFP-32 footprint.
