概要
説明
The 9FGU0231 is a member of IDT's 1.5 V Ultra-Low-Power PCIe clock family. The device has 2 output enables for clock management, 2 different spread spectrum levels in addition to spread off, and 2 selectable SMBus addresses.
特長
- LP-HCSL outputs; save 4 resistors compared to standard PCIe devices
- 23 mW typical power consumption; reduced thermal concerns
- OE# pins; support DIF power management
- 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 25 MHz crystal; supports tight ppm with 0 ppm synthesis error
- Configuration can be accomplished with strapping pins; SMBus interface not required for device control
- 3.3 V tolerant SMBus interface works with legacy controllers
- Space saving 4x4 mm 24-pin VFQFPN; minimal board space
- Selectable SMBus addresses; multiple devices can easily share an SMBus segment
