Our Family of Clock Buffers


We offer one of the most extensive selections of clock buffers with two to 22 outputs. These high-performance buffers support a variety of frequencies and industry-standard differential output formats such as Low-Voltage Positive/Pseudo Emitter-Coupled Logic (LVPECL); Low-Voltage Differential Signaling (LVDS); Low-Power, High-speed Current Steering Logic (LPHCSL); HCSL; Current-Mode Logic (CML); and single-ended Low-Voltage Complementary Metal-Oxide-Semiconductor (LVCMOS) outputs. These buffers have a maximum clock rate of 7 GHz and a data rate of 10.7 Gbps, with very low additive jitter. Our clock buffer family includes fanout buffers, low-jitter buffers, low-power-consumption buffers, zero-delay buffers and compliance with PCIe® and automotive application standards.

ZL40294B

Low-Jitter, Low-Power PCIe Buffer

The high-performance, ultra-low-jitter, low-power HCSL fanout buffer, with one to 20 outputs, is fully compliant with the DB2000QL standard and suitable for applications such as PCIe Gen 1–6 clock distribution, Intel® QPI servers, storage, data centers, switches and routers.

SYA75608

High-Performance Automotive Buffer

This ultra-low additive jitter, PCIe Gen 1–6-compliant clock buffer, with eight or 12 outputs for automotive applications operates at frequencies up to 250 MHz. It features low-power HCSL outputs with an embedded Low-Dropout (LDO) regulator for superior power noise supply rejection.

ZL40272

Low-Skew, Low-Jitter HCSL Buffer

This HCSL/LVDS/LVPECL fanout buffer with 12 outputs distributes clock signals with low jitter and low skew. The device operates at frequencies up to 625 MHz frequencies, making it suitable for high-speed applications such as telecommunications, data centers and networking equipment.

ZL40268

Low-Skew, Low-Jitter Differential ePPS Fanout Buffer

This clock fanout buffer offers ultra-low additive jitter of just 24 fs and supports frequencies up to 1.5 GHz. Well-suited for PCIe Gen 1–5 clock trees, it features eight outputs, hot-swappable capabilities and control via individual output pins or I2C interface.
