CY2DL814

ComLink™ Series CY2DL814 1:4 Clock Fanout Buffer Features Low-voltage operation VDD = 3.3V 1:4 Fanout Single-input configurable for — LVDS, LVPECL, or LVTTL — Four differential pairs of LVDS outputs Drives 50- or 100-ohm load (selectable) Low input capacitance Low output skew Does not exceed Bellcore 802.3 standards Operation at ⇒ 350 MHz – 700 Mbps Low propagation delay Typical (tpd < 4 ns) Industrial versions available Packages available include TSSOP/SOIC Description The Cypress CY2 series of network circuits is produced using advanced 0.35-micron CMOS technology, achieving the industry’s fastest logic. The Cypress CY2DL814 fanout buffer features a single LVDS-, LVPECL-, or LVTTL-compatible input and four LVDS output pairs. Designed for data-communication clock management applications, the fanout from a single input reduces loading on the input clock. The CY2DL814 is ideal for both level translations from single ended to LVDS and/or for the distribution of LVDS-based clock signals. The Cypress CY2DL814 has configurable input and output functions. The input can be selectable for LVPECL/LVTTL or LVDS signals while the output driver ’s support standard and high drive LVDS. Drive either a 50-ohm or 100-ohm line with a single part number/device.
