The SY89871UMG 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 frequency locked lower speed version of the input clock (Bank B).Available divider ratios are 2, 4, 8 and 16. In a typical 622MHz clock system this would provide availability of 311MHz, 155MHz, 77MHz, or 38MHz auxiliary clock components.
The differential input buffer has a unique internal termination design that allows access to the termination network through a VT pin. This feature allows the device to easily interface to different logic standards. A VREF-AC reference is included for AC-coupled applications.The SY89871U includes two phase-matched output banks. Bank A (QA) is a frequency-matched copy of the input. Bank B (QB0, QB1) is a divided down output of the input frequency. Bank A and Bank B maintain a matched delay independent of the divider setting.
