12-output DB1200Z Compliant Buffer

The IDT9ZX21201 is a 12-output DB1200Z suitable for PCI-Express Gen3 or QPI applications. The part is backwards compatible to PCIe Gen1 and Gen2. A fixed external feedback maintains low drift for critical QPI applications. In bypass mode, the IDT9ZX21201 can provide outputs up to 150MHz.

• Space-saving 64-pin packages
• Fixed feedback path/ 0ps input-to-output delay
• 9 Selectable SMBus Addresses/Multiple devices can share the same SMBus Segment
• 12 OE# pins/Hardware control of each output
• PLL or bypass mode/PLL can dejitter incoming clock
• 100MHz or 133MHz PLL mode operation/supports PCIe and QPI applications
• Selectable PLL bandwidth/minimizes jitter peaking in downstream PLL"s
• Spread Spectrum Compatible/tracks spreading input clock for low EMI
• Software control of PLL Bandwidth and Bypass Settings/ PLL can dejitter incoming clock (B Rev only)
