| RoHS: | Compliant |
This 3.3V low-skew, low-jitter, precision LVDS output clock divider accepts any high-speed differential clock input (AC- or DC-coupled) CML, LVPECL, HSTL or LVDS and divides down the frequency using a programmable divider ratio to create a frequency-locked, lower speed version of the input clock. The SY89873L includes two output banks. Bank A is an exact copy of the input clock (pass through) with matched propagation delay to Bank B, the divided output bank. 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 all AC- or DC-coupled differential logic standards. A VREF-AC reference is included for AC-coupled applications.The SY89873L is part of Micrel's high-speed Precision Edge® timing and distribution family. For 2.5V applications, consider the SY89872U. For applications that require an LVPECL output, consider the SY89871U.The /RESET input asynchronously resets the divider outputs (Bank B). In the pass-through function (Bank A) the /RESET synchronously enables or disables the outputs on the next falling edge of IN (rising edge of /N). Refer to the Timing Diagram.
