Tri-State

•

Output frequencies of 33.3, 66.6, 100 and 133.3

MHz selectable (PCIX requirements)

XIN

•

Output grouped in two banks of 5 clocks each.

I²C clock control interface for individual clock

disabling, SSCG control and individual bank

frequency selection

Tri-State

Note: A and B banks have separate frequency select

and output enable controls. XIN is the frequency of

the clock on the device’s XIN pin. OEA or OEB will

tristate REF.

•

Output clock duty cycle is 50% (± 5%)

<250 pS skew between output clocks within a

bank

•

Output jitter <250 pSec. (175pSec with all

outputs at the same frequency)

Pin Configuration

•

Spread Spectrum feature for reduced EMI

OE pins for separate output bank enable control

and testability
