A clock generator produces multiple low-jitter clock signals from a reference clock. The INS8214A is an ultra-low-power clock generator with an integrated fractional-N PLL. It supports multiple reference input types and multiple clock outputs, providing clocking solutions for high-speed systems such as PCIe and Ethernet applications.

Key Features

• Ultra-low power consumption with PLL and buffer operating modes
• Integrated fractional-N PLL with RMS jitter as low as 400 fs (typical, 12 kHz to 20 MHz, Fout = 100 MHz)
• Supports differential, LVCMOS, and crystal reference inputs from 10 MHz to 200 MHz
• Supports four differential clock outputs and one single-ended LVCMOS output
• Supports multiple output formats, including LVDS, LVPECL, LPHCSL, pCML, and LVCMOS
• Supports PCIe Gen1/2/3/4
• Supports spread-spectrum clocking (SSC)
• Supports DCO frequency adjustment with 10 ppb resolution
• Operating temperature range: -40°C to +105°C
• 24-pin VQFN package, 4.0 mm x 4.0 mm

Applications

• Communications equipment: Ethernet switches, network interface cards, and other networking equipment
• Data centers and servers: PCIe Gen1/2/3/4 systems and multi-clock distribution applications
• Industrial control: MCU-, SoC-, and FPGA-based control systems requiring multiple clock outputs
• Test and measurement: equipment requiring multiple low-jitter clock signals
