PI6C49S1504LIE

Clock Buffers, Drivers Overview

The PI6C49S1504LIE is a high-performance selectable 1:4 differential fanout buffer manufactured by Diodes Incorporated. It supports output frequencies up to 1.5 GHz for LVPECL and LVDS modes, and 250 MHz for HCSL mode. The device features four differential outputs organized into two configurable banks (A and B), allowing independent selection of signaling standards including LVDS, LVPECL, or HCSL. It includes an LVCMOS reference output capable of reaching 200 MHz. Key electrical specifications include ultra-low additive phase jitter (< 0.03 ps typ) and low propagation delay (typ < 1.5 ns). The component operates on dual power supplies (VDD and VDDO) ranging from 2.375 V to 3.465 V and is housed in a 28-pin TSSOP package.

Clock Buffers, Drivers Feature Summary

• Configurable Output Standards: Supports LVDS, LVPECL, or HCSL signaling for each of the two output banks via OpMode pins.
• High Frequency Performance: Differential outputs support up to 1.5 GHz; LVCMOS reference output supports up to 200 MHz.
• Low Jitter and Skew: Features ultra-low additive phase jitter (< 0.03 ps typ) and low output skew (< 40 ps within banks).
• Flexible Input Selection: Accepts single-ended, differential, or crystal inputs selected via CLK_SEL pins.

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 'E' indicates Pb-free and Green compliance, and 'X' denotes Tape & Reel packaging if applicable. Confirm the specific package variant matches the required manufacturing process. Ensure supply voltage requirements align with the 2.375 V to 3.465 V range for both core and output supplies.

Clock Buffers, Drivers Selection Notes

Select this component when distributing high-speed differential clocks with mixed signaling standard requirements across different system sections. The dual-bank architecture allows mixing LVDS and LVPECL outputs if needed. Ensure the design accounts for separate VDD and VDDO power domains and external termination resistors for LVDS/LVPECL configurations.

Clock Buffers, Drivers Part Context

The PI6C49S1504 belongs to the PI6C49S series of high-performance clock buffers from Diodes Incorporated (formerly Pericom). It is designed for applications demanding precise clock distribution with minimal jitter. The LIE suffix specifically identifies the 28-pin TSSOP package with industrial temperature rating (-40°C to +85°C) and RoHS-compliant construction.

Clock Buffers, Drivers Replacement Considerations

Check datasheets for other PI6C49S variants (e.g., PI6C49S1506) for pin compatibility and feature overlap. Verify that alternative components support the same combination of LVDS/LVPECL/HCSL outputs and frequency requirements.
