PI6C49S1510ZDIE

Clock Buffers, Drivers Overview

The PI6C49S1510ZDIE is a high-performance fanout buffer from Diodes Incorporated, housed in a 48-pin TQFN package. It supports differential output frequencies up to 1.5 GHz and features ten outputs divided into two banks. Each bank allows user-configurable signaling standards including LVDS, LVPECL, or HCSL via pin selection. The device includes an LVCMOS reference output capable of reaching 200 MHz. Key electrical parameters include a maximum propagation delay of 2.2 ns, a typical additive phase jitter of less than 0.03 ps at 156.25 MHz (12 kHz to 20 MHz range), and operation within a supply voltage range of 2.375 V to 3.465 V.

Clock Buffers, Drivers Feature Summary

• Ten differential outputs organized into two banks with selectable LVDS, LVPECL, or HCSL signaling standards.
• Ultra-low additive phase jitter specification: typically < 0.03 ps RMS at 156.25 MHz (12 kHz to 20 MHz integration range).
• Supports multiple input types including differential, single-ended, and crystal oscillators via IN_SEL configuration.
• Integrated illegal input detection logic that forces outputs to a low state upon detecting invalid input conditions.

Clock Buffers, Drivers Applications

• Networking systems such as switches and routers requiring precise clock distribution.
• High-frequency backplane-based computing platforms.
• Telecom infrastructure utilizing OC3/SONET signaling standards.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'E' confirms Pb-free and Green compliance for the PI6C49S1510ZDIE variant. Confirm the 'X' suffix indicates tape and reel packaging if required for automated assembly. Ensure the operating temperature range of -40 °C to +85 °C aligns with system thermal requirements. Cross-reference the 48-pin TQFN mechanical dimensions against the PCB footprint design.

Clock Buffers, Drivers Selection Notes

Select this component when distributing clocks up to 1.5 GHz with mixed interface requirements across different destination devices. The dual-bank architecture allows independent configuration of output standards, simplifying board layouts where LVDS and LVPECL loads coexist. Verify that the power supply filtering meets the recommended isolation guidelines to maintain the specified ultra-low jitter performance.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49S1510A series of high-performance differential fanout buffers. It is functionally equivalent to the PI6C49S1510 but packaged in the ZD (TQFN-48) format. The device utilizes proprietary input detection techniques to ensure robust operation by reflecting illegal input states through the output pins.

Clock Buffers, Drivers Replacement Considerations

The PI6C49S1510ZDIEX serves as the tape and reel version of the same functional device. Other members of the PI6C49S1510 family may offer different pin counts or package styles but share similar core specifications.

Clock Buffers, Drivers FAQ

How are the output signaling standards configured?

The signaling standard for each bank (Bank A and Bank B) is selected using the OPMODEA and OPMODEB pins. These pins support LVCMOS/LVTTL levels to select between LVPECL, LVDS, or HCSL modes.

What is the maximum frequency supported by the LVCMOS reference output?

The LVCMOS reference output (Ref_Out) supports frequencies up to 200 MHz when driven by a reference input, or up to 50 MHz when driven by a crystal oscillator.

How does the device handle illegal input conditions?

The PI6C49S1510 integrates a detection technique that identifies illegal input states, such as open inputs or both inputs being high/low. In these cases, the output status is forced to Logic Low.
