DIODES Incorporated Clock Generators, PLLs, Frequency Synthesizers PI6CG18401ZHIE

The PI6CG18401ZHIE is a low power PCIe clock generator designed for applications requiring high performance and low jitter outputs. It operates with a supply voltage of 1.8V and accepts a 25 MHz crystal or CMOS input to generate four differential HCSL outputs at 100 MHz, featuring on-chip termination that simplifies PCB layout by eliminating the need for external resistors. The device supports individual output enable controls and offers programmable slew rates and output amplitudes for each output, allowing for customization based on specific application needs. The clock generator is compliant with PCIe Gen1, Gen2, Gen3, and Gen4 standards, ensuring compatibility with a wide range of devices. It exhibits very low jitter characteristics, with differential cycle-to-cycle jitter less than 50 ps and output-to-output skew also under 50 ps. Additionally, the device includes a buffered reference output for low noise applications and supports selectable spread-spectrum options to mitigate EMI. Configuration can be achieved through strapping pins or an SMBus interface, which is 3.3V tolerant. The product is packaged in a 32-lead TQFN format, suitable for industrial applications.
