ISPPAC-CLK5620AV-01TN100I

The Lattice Semiconductor ISPPAC-CLK5620AV-01TN100I is an in-system programmable, enhanced zero-delay clock generator designed for high-performance applications. It features input/output operation from 8MHz to 400MHz with low output-to-output skew of less than 50ps and low peak-to-peak jitter.

This device offers up to 20 programmable fan-out buffers with selectable output standards including LVTTL, LVCMOS, HSTL, SSTL, LVDS, and LVPECL. It supports programmable output impedance and slew rate. The integrated high-performance PLL allows for programmable lock detect, multiply/divide ratios, and on-chip loop filter, and is compatible with spread spectrum clocks.

Precision programmable phase adjustment per output provides up to +/- 12ns skew range with 16 settings. The device supports up to five clock frequency domains and flexible clock reference and external feedback inputs. It is hot-socket compliant and stores four user-programmable profiles in E2CMOS memory. The ispPAC-CLK5620AV-01TN100I is available in a 100-TQFP package and operates over a commercial temperature range of -40°C to 85°C.

Applications include circuit board common clock generation and distribution, PLL-based frequency generation, high fan-out clock buffering, and zero-delay clock buffering.
