AN1125 - Interfacing the CYS25G0101DX to Differential LVPECL
AN1125 demonstrates how to connect the single-ended interface of CYS25G0101DX to a differential LVPECL device and provides simple formulas to help users calculate the values of the termination circuitry.
The CYS25G0101DX is a SONET OC-48 Transceiver. It provides complete parallel-to-serial and serial-to-parallel conversions, clock and data recovery, and clock synthesis functions in a single chip. The synchronous parallel input and output interface of the CYS25G0101DX are HSTL and LVCMOS compliant, and support differential and single ended LVPECL standards devices.
