Signal conditioners claim industry's highest performance at lowest power
January 31, 2012 // Paul Buckley
Texas Instruments Incorporated has introduced 10 signal conditioners designed to drive high-speed interface standards such as 10G/40G/100G Ethernet, 10G-KR (802.3ap), InfiniBand, Fibre Channel and CPRI. The ICs join a comprehensive family of repeaters and retimers that combat signal impairments caused by insertion loss, jitter, reflections and crosstalk in high-speed enterprise servers, routers and switches.
Manufactured using TI’s high-performance BiCMOS SiGe process technology, the new signal conditioners claim to deliver the industry’s highest signal reach performance at less than 6-mW per gigabit.
Key features and benefits of the DS1xxDF410, DS1xxRT410 and DS100KRxxx families include:
1) Extend reach to exceed 50+ inches of FR-4 backplane or 20 meters of 26-AWG copper cable:
- 36-dB input EQ and 12-dB output de-emphasis (DE)
- Multi-tap decision feedback equalizer (DFE
- Clock and data recovery (CDR) with internal clock synthesis
- Repeaters consume 65-mW per channel; retimers with CDR consume 150-mW per channel.
2) Reduce bill of materials (BOM) cost and simplify system design:
- Fully adaptive EQ simplifies link tuning.
- Internal clock synthesis avoids the need for an external reference clock.
- Built-in eye monitor and PRBS generator simplifies system debug.
- Single power supply without the need for external RF chokes.
The signal conditioners are used to drive optical and direct-attach passive copper cables in latency-sensitive, front-port line cards, while meeting SFF8431 (SFP+) specifications. They also can be used to compensate for loss and crosstalk in backplanes, and reduce gauge thickness in active copper cable assemblies. Offered as a pin-compatible IC family, system designers can choose from repeaters (EQ and DE driver), retimers (EQ, CDR and DE driver), and advanced retimers (EQ, CDR, DFE and DE driver) to achieve the desired link performance and system cost without having to redesign their board:
- The DS125DF410 (9.8G to 12.5G), DS110DF410 (8.5G to 11.3G) and DS100DF410 (10.3G) multi-rate quad-channel advanced retimers provide multi-tap DFE, adaptive EQ, CDR, and DE driver.
- The DS125RT410 (9.8G to 12.5G), DS110RT410 (8. 5G to 11.3G) and DS100RT410 (10.3G) multi-rate quad-channel retimers provide adaptive EQ, CDR, and DE driver.
- The DS100KR800 octal-channel (unidirectional) and DS100KR401 octal-channel (bidirectional) repeaters support x4/x8 10G-KR (802.3ap) connectivity, and seamlessly allow end-to-end transmit equalization negotiation between the host controller and endpoint as specified by the 802.3ap standard.
To support redundancy and fail-over applications, TI offers new 10.3G and 14.2G mux/buffers that support two- and four-port switching capability. Both devices support 10G-KR transmit link training:
- The DS100MB203 multi-rate, dual lane 2:1/1:2 mux/buffer provides EQ and DE and supports data rates up to 10.3G.
- The SN65LVCP114 quad-lane 2:1/1:2 mux/buffer provides a linear EQ and supports data rates up to 14.2G.
TI also offers the TLK10002 10G multi-rate transceiver, LMK03806 clock generator, and SIMPLE SWITCHERs and temperature sensors to complement the signal conditioners in a system.
Evaluation modules are also available as well as IBIS-AMI simulation models for the retimers, and H-Spice models for the repeaters and mux/buffer.
The ICs are sampling now, with volume production scheduled for late first quarter 2012. The DS1xxDF410 and DS1xxRT410 quad-channel retimers are offered in 7-mm x 7-mm, 48-pin leadless LLP packages, and the DS100KRxxx octal-channel repeaters and DS100MB203 dual-lane mux/buffer are supplied in 10-mm x 5.5-mm, 54-pin LLPs. The SN65LVCP114 quad-lane mux/buffer is packaged in a 12-mm x 12-mm, 167-pin BGA.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
