Features
- PCIe Gen1–4 compliant
- Integrated terminations provide 100Ω differential Zo: reduced component count and board space
- 1.8V operation: reduced power consumption
- Outputs can optionally be supplied from any voltage between 1.05V and 1.8V: maximum power savings
- OE# pins: support DIF power management
- LP-HCSL differential clock outputs: reduced power and board space
- Programmable slew rate for each output: allows tuning for various line lengths
- Programmable output amplitude: allows tuning for various application environments
- DIF outputs blocked until PLL is locked: clean system start-up
- Selectable 0%, -0.25% or -0.5% spread on DIF outputs: reduces EMI
- External 25MHz crystal; supports tight ppm with 0ppm synthesis error
- Configuration can be accomplished with strapping pins: SMBus interface not required for device control
- 3.3V tolerant SMBus interface works with legacy controllers
- Space-saving 6 × 6 mm 48-VFQFPN; minimal board space
- Selectable SMBus addresses: multiple devices can easily share an SMBus segment
- Available in AEC-Q100 qualified, Grade 2 (-40°C to +105°C) version (wettable flank package)
