Features
GENERAL
- Low power, 4 channel, bi-directional, full duplex, 2.125 - 3.2 Gbit/s retimer compliant with the
10 Gigabit Ethernet (10GE) and proposed 10 Gigabit Fibre Channel (10GFC) standards.
- Ideal for 10GE, 10GFC, and InfiniBand applications for extending the reach of high-speed serial links across a backplane.
- Small form factor and low power are suitable for retiming inside a 10GBase LX4 optical module.
- Four channels can be trunked to form one logical link for XAUI retimer applications.
- 8B/10B encoders/decoders can be bypassed for retiming of scrambled NRZ data streams.
|
- Supports non-blocking cross-connect to enable flexible configuration as a re-timer or cross-connect.
- Pin-configurable for standalone operation.
- Integrated serializer/deserializer, clock synthesis, clock recovery and 8B/10B encode/decode logic.
- Supports differential AC-coupled PECL-level REFCLK.
|
HIGH-SPEED SERIAL INTERFACE
- Programmable receiver equalization to minimize the effects of Inter Symbol Interference (ISI).
- Programmable transmit pre-emphasis to counteract dielectric losses and allow maximum reach on printed circuit boards.
|
- Integrated termination resistors to directly drive 100 ohm differential traces.
|
TEST FEATURES
- Extensive control of loopback, BIST and operating modes via 802.3ae-compliant MDC/MDIO serial interface (1.2 V compliant).
- On-chip packet generator/checker provides at-speed diagnostics.
- Built-in error counters per channel.
|
- Support for IEEE 1149.1 JTAG testing on all pins.
- Comprehensive evaluation platform for easy customer qualification.
|
