    摘要: A high-linearity Phase Interpolator based Clock and Data Recovery (CDR) circuit for use in a multi-standard Serializer/Deserializer (SerDes) is provided. By interpolating at a high, fixed frequency for all supported data rates and then dividing the output clock down to the appropriately frequency for each standard, the Phase Interpolator can provide for maximum phase linearity while reducing its sensitivity to noise.

    摘要: A memory interface enables AC characterization under test conditions without requiring the use of Automated Test Equipment (ATE) and functional patterns. The memory controller may be configured to generate output patterns through the test interface and create a loopback path for input specification testing using an external stressed-eye random number generator and checker. As a result, the memory interface may be evaluated for electrical and timing specifications under a relatively simple test setup and test procedure through the test interface (JTAG), as opposed to a complex processor program that sets up a similar memory access pattern on Automated Test Equipment (ATE).
