描述
The 951464 is a main clock synthesizer chip that provides all clocks required for ATI RS/RD690-based systems. An SMBus interface allows full control of the device.
特性
- 2 - 0.7V current-mode differential CPU pairs
- 6 - 0.7V current-mode differential SRC pairs
- 2 - 0.7V current-mode differential ATIG pairs
- 1 - HyperTransport clock seed
- 2 - 48MHz USB clock
- 3 - 14.318MHz Reference clock
- CPU outputs cycle-to-cycle jitter < 85ps
- SRC outputs cycle-to-cycle jitter < 125ps
- ATIG outputs cycle-to-cycle jitter < 125ps
- +/- 300ppm frequency accuracy on CPU, SRC & ATIG clocks
- 3 - Programmable Clock Request pins for SRC and ATIG clocks
- ATIGCLKs are programmable for frequency
- Spread Spectrum for EMI reduction
- Outputs may be disabled via SMBus
- External crystal load capacitors for maximum frequency accuracy
