## Description
The CDC536 is a high-performance, low-skew, low-jitter clock driver that utilizes a phase-lock loop (PLL) to align clock output signals with the input clock (CLKIN). It’s designed for synchronous DRAMs and microprocessors operating from 50 MHz to 100 MHz (or down to 25 MHz with half-frequency outputs). The feedback input (FBIN) synchronizes output clocks to the input.

## Functional Details
️· PLL Operation: Precisely aligns clock outputs to the input frequency and phase.
️· Output Configuration: Select (SEL) input configures outputs to operate at half or double the input frequency.
️· Feedback Input (FBIN): Required for PLL synchronization; connected to one of the six output clocks.
️· Output Enable (OE): Controls output state (active or high-impedance).
️· Test Input (TEST): Used for factory testing; bypasses PLL.
