Microchip Technology, Inc. 6-Output PCIe Clock Generator ZL30282

The ZL30282 is a high-performance PCIe Gen 1-4 clock generator. From a 50MHz crystal or CMOS input these devices generate 100 MHZ in four pre-programmed output configurations immediately on power-up to 6 differential outputs. The devices have industry-leading output jitter of 160fs RMS (12kHz to 20MHz). Additional Features 50MHz crystal or CMOS input Generates PCIe 1, 2, 3, 4, 5 compliant clocks Spread-spectrum clocks (SSC) and regular clocks at the same time (configs 5-8) Output jitter <0.3ps rms 12kHz-20MHz typical for non-spread-spectrum outputs Up to 6 output clocks with 8 default configurations selected by hardware pins at reset: (Configs 0-3 no SSC, Configs4-7 SSC for OC3-6) Config0/4: OC1 100MHz HCSL, OC2_P 25MHz LVCMOS, OC3/4/5 unused, OC6 100MHz HCSL Config1/5: OC1 100MHz HCSL, OC2_P 25MHz LVCMOS, OC3/4/5/6 100MHz HCSL Config2/6: OC1 100MHz HCSL, OC2_P 75MHz LVCMOS, OC3/4/5/6 100MHz HCSL Config3/7: OC1/2 100MHz HCSL, OC3/4/5/6 100MHz HCSL Per-output control via SPI or I2C interface Precise output alignment circuitry and per-output phase adjustment Per-output enable/disable and glitch-less start/stop (stop high or low) Spread-spectrum enable/disable for DIV2 Core supply voltage options: 2.5V only, 3.3V only, 1.8V+2.5V or 1.8V+3.3V Space-saving 8x8mm QFN56 (0.5mm pitch)
