LU5X34F Datasheet PDF - Agere -> LSI Corporation

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.
