Microchip ZL40272: High-Performance Clock Fanout Buffer

The Microchip ZL40272 is an advanced, low-skew, low additive jitter, 12-output fanout buffer designed for critical clock distribution applications. It supports HCSL, LVDS, and LVPECL output formats, offering flexibility for various system requirements.

Key features include:

Low Jitter: Ultra-low additive jitter of 24 fs (12 kHz to 20 MHz).
Flexible Inputs: A 3-to-1 input multiplexer accepts differential (LVPECL, HCSL, LVDS, SSTL, CML, LVCMOS) or single-ended signals, and a crystal oscillator input.
Multiple Outputs: Twelve differential HCSL/LVDS/LVPECL outputs.
Control: Programmable via I2C bus or hardware control pins.
Applications: Ideal for PCIe Gen1-7 clock distribution, wired communications (OTN, SONET/SDH, GE), wireless communications, and high-performance microprocessor clocking.
