Description

The PI6C2504AQEX is a low-skew, low-jitter, phase-locked loop (PLL) clock driver designed for distributing high-frequency clock signals for SDRAM and server applications. It features a feedback loop that ensures nearly zero propagation delay from the CLK_IN input to any clock output.

Specifications and features

- High-Performance Phase-Locked-Loop Clock Distribution for Networking
- Registered DIMM Synchronous DRAM modules for server/workstation/PC applications
- Allows Clock Input to have Spread Spectrum modulation for EMI reduction
- Zero Input-to-Output delay
- Low jitter: Cycle-to-Cycle jitter –75ps max.
- On-chip series damping resistor at clock output drivers for low noise and EMI reduction
- Operates at 3.3V VCC
- Wide range of Clock Frequencies 80 to 134 MHz
- Package: Plastic 16-pin QSOP Package (Q)

Application Scenarios

The PI6C2504AQEX is ideal for use in networking applications that require high-performance phase-locked-loop clock distribution. It is also suitable for server, workstation, and PC applications that use registered DIMM synchronous DRAM modules. Additionally, its spread spectrum modulation capability makes it effective in reducing electromagnetic interference (EMI).

Comparison

- Zero input-to-output delay ensures accurate and reliable clock distribution.
- Low skew and jitter minimize timing errors in high-frequency clock signals.
- On-chip damping resistor reduces noise and EMI for improved signal integrity.
- Wide range of clock frequencies allows flexibility in system design.

- Limited to 16-pin QSOP package, which may not be compatible with all system designs.
