Features

? Jitter below 100fs RMS maximum (10kHz to

20MHz)

? PLL core consists of fractional-feedback Analog

PLL (APLL) which can optionally be steered by a

Digital PLL (DPLL)

○ Operates from an integrated 60MHz crystal

○ APLL frequency independent of input / crystal

frequency

○ Operates as a frequency synthesizer, jitter

attenuator, or Digitally Controlled Oscillator

(DCO)

○ DPLL loop filter programmable from 10Hz to

12kHz

○ DCO has tuning granularity of < 1ppb

? Programmable input buffer supports HCSL, LVDS,

or two LVCMOS with no external terminations

needed

○ Input frequencies: 1MHz to 800MHz (250MHz for

LVCMOS)

○ Reference monitor qualifies/disqualifies input

clock

? Programmable status output

? 4 differential / 8 LVCMOS outputs

○ Any frequency from 10MHz to 1GHz (180MHz for

LVCMOS)

○ Programmable output buffer supports HCSL (DCcoupled), LVDS/LVPECL/CML (AC-coupled) or

two LVCMOS

○ Differential output swing is selectable: 400mV to

800mV

○ Output Enable input with programmable effect

? Supports up to 1MHz I2C or up to 20MHz SPI serial

processor port

? Can configure itself automatically after reset via

internal customer-definable One-Time

Programmable (OTP) memory with up to four

different configurations

? 4 × 4 mm 28-QFN package
