ICS2510C

The ICS2510C is a high performance, low skew, low jitter clock driver. It uses a phase lock loop (PLL) technology to align, in both phase and frequency, the CLKIN signal with the CLKOUT signal. It is specifically designed for use with synchronous SDRAMs. The ICS2510C operates at 3.3V VCC and drives up to ten clock loads.

One bank of ten outputs provide low-skew, low-jitter copies of CLKIN. Output signal duty cycles are adjusted to 50 percent, independent of the duty cycle at CLKIN. Outputs can be enabled or disabled via control (OE) inputs. When the OE inputs are high, the outputs align in phase and frequency with CLKIN; when the OE inputs are low, the outputs are disabled to the logic low state.

The ICS2510C does not require external RC filter components. The loop filter for the PLL is included on-chip, minimizing component count, board space, and cost. The test mode shuts off the PLL and connects the input directly to the output buffer. This test mode, the ICS2510C can be use as low skew fanout clock buffer device. The ICS2510C comes in 24 pin 173mil Thin Shrink Small-Outline package (TSSOP) package.
