Overview

The LU5X34F is a low-cost, low-power quad transceiver. It is used for data transmission over fiber or coaxial media in conformance with IEEE* 802.3z Gigabit Ethernet specification and Fibre Channel ANSI† X3T11 at 1.0 Gbits/s and 1.25 Gbits/s.

Features

■ Designed to operate in Ethernet, fibre channel, Firewire‡, or backplane applications.

■ Operationally compliant to IEEE 802.3z Gigabit Ethernet specification.

■ Operationally compliant to Fibre Channel ANSI X3T11. Provides FC-0 services at 1.0 Gbits/s— 1.25 Gbits/s (10-bit encoded data rate).

■ 100 MHz—125 MHz differential or single-ended reference clock.

■ 10-bit parallel, TTL-compatible I/O interface.

■ 8-bit/10-bit encoded data.

■ High-speed comma character recognition (K28.1, K28.5, K28.7) for latency-sensitive applications and alignment to word boundary.

■ Two 50 MHz—62.5 MHz receive-byte clocks.

■ Single analog PLL design requires no external components for the frequency synthesizer.

■ Novel digital data lock in receiver avoids the need for multiple analog PLLs.

■ Expandable beyond four serializer/deserializers.

■ PECL high-speed interface I/O for use with optical transceiver or coaxial copper media.

■ Requires one external resistor for PECL output reference-level definition.

■ Low-power digital CMOS technology.

■ Less than 2 W total power dissipation per quad transceiver.

■ 3.3 V ± 5 power supply.

■ 0 °C—70 °C ambient temperature.

■ Stand-alone transceiver product.

■ Transceiver macrocell template.

■ Available in 217-pin PBGA package.
