? Compliant with ITU-T G.8262 and G.8262.1

option 1 and 2 for synchronous Ethernet

Equipment Clock (EEC/eEEC) without degrading

output jitter

? PCIe Gen 1-6 CC, SRIS and SRNS support

? Jitter attenuation with programmable loop

bandwidth from 0.1Hz to 12kHz

? Up to four fractional output dividers and 12 integer

output dividers

? Each fractional output divider can be slaved with

DPLL or SYS-DPLL or free-run locked to APLL

? DPLL can be configured as DCO and each

fractional output divider can be configured as NCO

or DCO

? Combo bus allows frequency sharing between

DPLL, System DPLL, and each of the four

fractional output dividers

? LVCMOS, LVPECL, LVDS, HCSL, CML, SSTL,

HSTL output modes supported with programmable

output swing and common mode voltage

? JESD204B/C support on differential or single

ended outputs with DC-coupling or AC-coupling

? Up to seven single-ended or two differential clock

inputs, one crystal/XO input, and one

XO/TCXO/OCXO input

? Up to nine GPIO pins programmable to device

select or system monitor options

? Supports 1MHz I2C, 400kHz SMBus, or 50MHz

SPI serial port

? Internal non-volatile memory (up to 16 different

configurations), or external serial I2C EEPROM

provide default device settings on power-up.

? 2.5V and 3.3V core and 1.8V, 2.5V, and 3.3V

output operation

? -40° to +85°C industrial temperature operation
