Maxim lancerer 40G chipsæt
Maxim nye 40 Gbit/s chipsæt booster data throughput'et og reducerer effektforbruget (in english).
Maxim Integrated Products announces a 40G transmitter chipset that provides data centers with 4x the data throughput, at very low power, and in little more space than conventional single-channel alternatives. The new 4-channel 40GBASE-LR4 QSFP+ chipset comprises the MAX3948 DC-coupled laser driver and the DS4830 optical microcontroller.
Data centers and data communication networks need to significantly increase data density while staying within their already constrained power budgets. Maxim’s QSFP+ transmitter solution addresses both challenges. The QSFP+ modules supply 4x the data throughput in only 1.5x the area of a single-channel SFP+ solution.
Equally important, Maxim’s chipset enables 4 x 10Gbps QSFP+ modules to consume less power per channel than single SFP+ modules. Service providers and network operators can now enjoy the benefits of a low-power solution that extends system life, reduces operational expense, and conserves valuable energy resources.
MAX3948 key advantages:
• Consumes less than 2W for 4 transmit channels, enabling less than 3.5W QSFP+ module power consumption.
• DC-coupled laser interface (patent-pending, application number 13/352,011) reduces power consumption and external component count.
DS4830 Key Advantages:
• On-chip 13-bit ADC with dedicated round-robin offloads 16-bit microcontroller core and lowers clock speed; saves 75mW to 100mW compared to competitive solutions.
• Single-cycle multiply accumulator (MAC) allows DS4830 to speed through filter calculations and easily maintain four average power control (APC) loops.
