            HCSL Output Clock Oscillators
                    CTS models 643H and 645H are designed to support PCI Express® high-speed bus architectures
    

CTS Corporation’s low jitter clock oscillator models 643H and 645H are low noise differential devices offering high-speed current steering logic (HCSL) output. HCSL outputs are found in high-speed bus architectures such as PCI Express (PCIe®) interfaces and high definition video applications primarily supported by Intel® and Nvidia® chipsets.

CTS models 643H and 645H offer stability options of ±20 ppm, ±25 ppm, ±30 ppm, ±50 ppm, and ±100 ppm, input voltages at +2.5 V or +3.3 V and typical phase jitter performance of <500 fs. Along with standard commercial and industrial temperature range options, these models also support the extended range of -40°C to +105°C for fanless applications.
