3.3V Phase-Lock Loop Clock Driver
Pin Configuration
The ICSVF2510 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 ICSVF2510 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 ICSVF2510 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 ICSVF2510
can be use as low skew fanout clock buffer device. The
ICSVF2510 comes in 24 pin 173mil Thin Shrink Small-
Outline package (TSSOP) package.
