ISPPAC-CLK5620AV-01TN100C

The Lattice Semiconductor ISPPAC-CLK5620AV-01TN100C is a high-performance, in-system-programmable clock generator designed for demanding communication and computing applications. It offers a wide input/output operation frequency range from 8MHz to 400MHz, with low output-to-output skew and jitter.

This device features up to 20 programmable fan-out buffers with support for various output standards including LVTTL, LVCMOS, HSTL, and LVDS. It also includes a fully integrated high-performance PLL with programmable lock detect and on-chip loop filter. The programmable output impedance ranges from 40 to 70 Ohms, and slew rate is also programmable.

With up to 10 banks supporting individual VCCO and GND, and flexible clock reference and external feedback inputs, the ISPPAC-CLK5620AV-01TN100C provides significant design flexibility. It supports multiple clock frequency domains and offers precision programmable phase adjustment for skew control. The device is available in a 100-pin TQFP package and operates within a commercial temperature range of 0°C to 70°C.

Applications include circuit board common clock generation and distribution, PLL-based frequency generation, high fan-out clock buffering, and zero-delay clock buffering. All inputs and outputs are hot-socket compliant, and the device stores four user-programmable profiles in E2CMOS memory.
