Product Summary
The CDC2536DBR is a high-performance, low-skew, low-jitter clock driver. It uses a phase-lock loop (PLL) to precisely align, in both frequency and phase, the clock output signals to the clock input (CLKIN) signal. It is specifically designed for use with synchronous DRAMs and popular microprocessors operating at speeds from 50 MHz to 100 MHz or down to 25 MHz on outputs configured as half-frequency outputs. The CDC2536DBR operates at 3.3-V VCC and is designed to drive a 50Ω transmission line. The CDC2536DBR also provides on-chip series-damping resistors, eliminating the need for external termination components.
