RENESAS 9ZX21200AKLF

The 9ZX21200 is a small-footprint 12-output differential buffer that meets all the performance requirements of the Intel DB1200Z specification. The 9ZX21200 is backwards compatible to PCle Gen1 and Gen2 applications. A fixed, internal feedback path maintains low drift for critical QPI applications. In bypass mode, the 9ZX21200 can provide outputs up to 150MHz.

• Space-saving 56-pin package
• Fixed feedback path for Ops input-to-output delay
• 9 Selectable SMBus Addresses; Mulitple devices can share the same SMBus Segment
• 4 OE# pins; Hardware control of four outputs
• PLL or bypass mode; PLL can dejitter incoming clock
• 100MHz or 133MHz PLL mode operation; supports PCle 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)
• 12 - 0.7V differential HCSL output pairs

• 12-output PCle Gen3/ QPI differential buffer for Romley and newer platforms
