描述
The 9ZXL1251 meets the demanding requirements of the Intel DB1200ZL specification, including the critical low-drift requirements of Intel CPUs. It is pin-compatible with the 9ZXL1231 and integrates 24 termination resistors, saving 41mm² board area.
特性
- 85Ω low-power push-pull HCSL outputs; eliminate 24 resistors, save 41mm² of area
- Pin-compatible with 9ZX21201 and 9ZXL1231; easy path to power and area savings
- Space-saving 64-pin VFQFPN package
- Fixed feedback path for 0 ps 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; supports common and separate clock architectures
- Selectable PLL bandwidth; minimizes jitter peaking in downstream PLLs
- Spread spectrum compatible; tracks spreading input clock for low EMI
- -40 °C to +85 °C device available; supports demanding environmental applications
