8A34041
Overview
- Each can act as a frequency synthesizer, jitter attenuator, Digitally Controlled Oscillator (DCO), or Digital Phase Lock Loop (DPLL)
- DPLL Digital Loop Filters (DLFs) are programmable with cut off frequencies from 1.1Hz to 22kHz
- Generates output frequencies that are independent of input frequencies via a Fractional Output Divider (FOD)
- Each FOD supports output phase tuning with 50ps resolution; 12 Differential / 24 LVCMOS outputs
- Frequencies from 0.5Hz to 1GHz (250MHz for LVCMOS)
- Jitter below 150fs RMS (10kHz to 20MHz)
- LVCMOS, LVDS, LVPECL, HCSL, CML, SSTL, and HSTL output modes supported
- Differential output swing is selectable: 400mV / 650mV / 800mV / 910mV
- Independent output voltages of 3.3V, 2.5V, or 1.8V; LVCMOS additionally supports 1.5V or 1.2V
- The clock phase of each output is individually programmable in 1ns to 2ns steps with a total range of ±180°; 8 differential / 16 single-ended clock inputs
