2. Detailed Features

2.1 Input Clock Features

 Four input clocks: one crystal/CMOS, two differential/CMOS, one single-ended/CMOS

 Input clocks can be any frequency from 9.72MHz up to 1250MHz (differential) or 300MHz (CMOS)

2.2 APLL Features

 Very high-resolution fractional (i.e. non-integer) multiplication

 Any-to-any frequency conversion with 0ppm error

 Two high-speed dividers (integers 4 to 15, half divides 4.5 to 7.5)

 Easy-to-configure, completely encapsulated design requires no external VCXO or loop filter

components

 Bypass mode supports system testing

2.3 Output Clock Features

 Three low-jitter output clocks

 Each output can be one differential output or two CMOS outputs

 Output clocks can be any frequency from 1Hz to 1035MHz (250MHz max for CMOS and HSTL outputs)

 Output jitter as low as 0.16ps RMS (12kHz to 20MHz integration band)

 In CMOS mode, an additional divider allows the OCxN pin to be an integer divisor of the OCxP pin

(example: OC3P 125MHz, OC3N 25MHz)

 Outputs easily interface with CML, LVDS, LVPECL, HSTL, SSTL, HCSL and CMOS components

 Supported telecom frequencies include PDH, SDH, Synchronous Ethernet, OTN
