MAX3984 Datasheet | Maxim Integrated

.. 19-0868; Rev 0; 7/07 1Gbps to 10Gbps Preemphasis Driver with Receive Equalizer General Description The MAX3984 is a single-channel, preemphasis driver with input equalization that operates from 1Gbps to 10.3Gbps. It provides pensation for copper links, such as 8.5Gbps Fibre Channel and 10.3Gbps Ethernet, allowing spans of up to 10m with 24 AWG cable. The driver provides four selectable preemphasis levels, and the selectable input equalizer pensates for up to 10in of FR-4 circuit board material at 10Gbps. The MAX3984 also Features SFP-pliant loss-of-signal (LOS) detection and TX_DISABLE. Selectable output swing reduces EMI and power consumption. The MAX3984 is packaged in a lead-free, 3mm x 3mm, 16-pin thin QFN and operates from a 0°C to +85°C temperature range. - Drives Up to 10m of 24 AWG Cable - Drives Up to 30in of FR-4 - Selectable 1000m VP-P or 1200m VP-P Differential Output Swing - Selectable Output Preemphasis - Selectable Input Equalization - LOS Detection with Built-In Squelch - Transmit Disable - Hot Pluggable Features Applications 8.5Gbps Fibre Channel 10.3Gbps Ethernet Active Cable Assemblies STM-64 PART MAX3984UTE+ Ordering Information TEMP RANGE PIN-PACKAGE PKG CODE T1633F-3 0°C to +85°C 16 Thin QFN-EP- Pin Configuration appears at end of data sheet. +Denotes a lead-free package. - EP = Exposed pad.
