Description

The DS32EL0124/DS32ELX0124 integrates clock and data recovery modules for high-speed serial communication over FR-4 printed circuit board backplanes, balanced cables, and optical fiber. This easy-to-use chipset integrates advanced signal and clock conditioning functions, with an FPGA friendly interface.

The DS32EL0124/DS32ELX0124 deserializes up to 3.125 Gbps of high speed serial data to 5 LVDS outputs without the need for an external reference clock. With DC-balance decoding enabled, the application payload of 2.5 Gbps is deserialized to 4 LVDS outputs.

The DS32EL0124/DS32ELX01214 deserializers feature a remote sense capability to automatically signal link status conditions to its companion DS32EL0421/ELX0421 serializers without requiring an additional feedback path.

The parallel LVDS interface of these devices reduce FPGA I/O pins, board trace count and alleviates EMI issues, when compared to traditional single-ended wide bus interfaces.

The DS32EL0124/ELX0124 is programmable through a SMBus interface as well as through control pins.
