SY89871U Overview
Description
The SY89871U is a 2.5V/3.3V LVPECL output precision clock divider capable of accepting a high-speed differential clock input (AC or DC-coupled) CML, LVPECL, HSTL or LVDS clock input signal and dividing down the frequency using a programmable divider ratio to create a frequencylocked lower speed version of the input clock (Bank B). Available divider ratios are 2, 4, 8, and 16.
Key Features
- Two matched-delay outputs
- Bank A: undivided pass-through (QA)
- Bank B: programmable divide by 2, 4, 8, 16 (QB0, QB1)
- Matched delay: all outputs have matched delay, independent of divider setting
- Guaranteed AC performance
- >2.5GHz fMAX
- <250ps tr/tf
- <670ps tpd (matched delay)
- <15ps within-device skew
- Low jitter design
