Repeater family run on third-generation SiGe BiCMOS process
National Semiconductor, a power management technology and analog integrated circuits provider, has released DS100BR410, DS100BR111 and DS100BR120 multi-channel PowerWise 10 Gbps repeaters.
The company said the repeaters provide an equalisation gain of 36 dB, consume 55 mW/channel of power and deliver 20 meters over 24-AWG cable reach of current industry offerings.
According to the company, the new 10 Gbps repeater family runs on National’s third-generation SiGe BiCMOS process that extends interconnect reach and enables higher data bandwidth up to 10.3125 Gbps by performing both receive equalisation and transmit de-emphasis to compensate for channel loss in data center and high-performance communication systems.
Target applications include high-speed active cable assemblies and FR-4 backplanes using serial protocols such as 10 GbE, Fibre Channel, XAUI, CPRI and Infiniband. The repeaters also support SAS/SATA out of band (OOB) signaling for storage applications, the company said.
National Semiconductor claims that its signal conditioners embedded inside the active copper cable assemblies and backplane boards ensure signal integrity, reduce system power consumption and lower interconnect cost compared to optical alternatives.
The company said, quad DS100BR410 is ideal for high density connectors such as QSFP and CXP, while the DS100BR111 is designed for single lane SFP+ connectors.
The DS100BR410 includes four unidirectional channels and delivers 55 mW/channel typical power consumption, while supporting a 2.5V single-supply voltage, said the company.
The DS100BR210 with two unidirectional channels and the DS100BR111 with one bidirectional lane feature 65mW per channel typical power consumption and support 3.3V and 2.5V supplies.
Both devices perform receive equalisation up to 36 dB gain and transmit de-emphasis of -12dB. All three repeaters enable powering down of unused channels, and apply signal conditioning settings via pin setting or SMBus (I2C compliant), said the company.
