特性
- Integrated terminations
- 85Ω transmission lines require 0 termination resistors
- 100Ω transmission lines require only 2 series resistors per output
- OE pin for each output supports CLKREQ# applications
- Intelligent power-down mode when all OE# pins are high (all outputs off)
- Spread-spectrum tolerant
- Open drain LOS# output indicates a loss of the input clock and returns the outputs to a Low/Low state
- Flexible power sequencing: Input clock is internally biased so a floating input clock will not inject noise into the system
- Power Down Tolerant: Control inputs will not clamp to ground or VDD if a signal is applied before chip VDD is applied
- Space saving 3mm × 3mm 16-VFQFPN
- Easy AC coupling to other logic families; see application note AN-891.
9DBL0255_9DBL0455 - Block Diagram
描述
The 9DBL0255 device is a 2-output PCIe clock fanout buffer for PCIe Gen 1–7 applications. It has an open drain Loss of Signal (LOS) output to indicate the absence or presence of an input clock.
