Integrated Circuit Systems, Inc. ICSVF2510 3.3V Phase-Lock Loop Clock Driver The ICSVF2510 is a high performance, low skew, low jitter • Meets or exceeds PC133 registered DIMM clock driver. It uses a phase lock loop PLL technology to specification1.1 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 • • Spread Spectrum Clock Compatible Distributes one clock input to one bank of ten outputs VCC and drives up to ten clock loads. • Operating frequency 20MHz to 200MHz 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. • • External feedback input FBIN terminal is used to synchrionize the outputs to the clock input No external RC network required Outputs can be enabled or disabled via control OE • Operates at 3.3V Vcc inputs. When the OE inputs are high, the outputs align in phase and frequency with CLKIN when the OE inputs are Plastic 24-pin 173mil TSSOP package 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 SmallOutline package TSSOP package.
