40G chipset reduces power consumption to boost data-center throughput
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.
The MAX3948 consumes less than 2 W for four transmit channels, enabling less than 3.5 W QSFP+ module power consumption. The DC-coupled laser interface reduces power consumption and external component count.
The DS4830’s on-chip 13-bit ADC with dedicated round-robin offloads 16-bit microcontroller core and lowers clock speed; saves 75 mW to 100 mW compared to competitive solutions. The device’s single-cycle multiply accumulator (MAC) allows DS4830 to speed through filter calculations and easily maintain four average power control (APC) loops.
