M21441
10.3125 Gbps Twelve-Channel Backplane Equalizer and Driver with 12x12 Crosspoint Switch and Integrated Clock Data Recovery (CDR)
Description
The M21440/M21441 are eight/twelve channel equalizers and CDRs designed to operate up to 10.3125 Gbps. The devices feature specialized ports for both backplane and intra-PCB communications. On the backplane side, the M2144x is equipped with high-performance inputs featuring an adaptive Continuous Time Linear Equalizer (CTLE) and an adaptive Decision Feedback Equalizer (DFE). Each channel has a programmable output driver, with post-tap and pre-tap de-emphasis (up to 12 dB total). The devices are designed to compensate for 10GBase-KR electrical backplanes.
To counter the effects of non-equalizable jitter, the M21440/M21441 are equipped with sophisticated clock and data recovery (CDR) circuits. The CDRs are equipped with auto-rate detect, further reducing configuration requirements. The M2144x is able to support many proprietary data rates up to 10.3125 Gbps. The M21440/M21441 also provides the user with a full suite of link assessment tools including loopbacks, pattern generator/checker, and post-equalization eye monitors. All devices feature fully non-blocking crosspoint switch cores that allow any input of the device to be connected to any output without restriction.
