Note 1:
“Absolute Maximum Ratings” are the ratings beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits.
Note 2:
Typical parameters are measured at nominal supply levels and T
A
= 25°C. They are for reference purposes and are not production-tested.
Note 3:
Transmit Jitter testing methodology is defined in Appendix 48B of IEEE 802.2ae-2002. The SCAN12100 transmit output jitter is constant for all valid CPRI
datarates. The transmit jitter is significantly less than the specified limits in terms of UI.
Note 4:
CJPAT is a stress pattern defined in IEEE 802.2ae-2002 Appendix 48A
Note 5:
CDET nominal valid duration is determined by the CPRI data rate. CDET timing is similar to the ROUT[0:9] timing.
Note 6:
Transmit or Receive K28.5 pattern. Assumes TXCLK is stable and toggles only after all SerDes clocks become synchronous.
Note 7:
Transmit latency is fixed once the link is established and is guaranteed by the Tser specification.
Note 8:
Receive latency is fixed once the link is established and is guaranteed by the Tdes specification.
Note 9:
Receiver output timing specifications for TS-R and TH-R are tested at the CPRI rate of 1.2288 Gbps.
Note 10:
Limits are guaranteed by design and characterization over process, supply voltage, and temperature variations.
Note 11:
Limits are guaranteed by design.
Note 12:
Serial side DCM readings are referenced to the first bit of the K28.5 pattern {110000 0101 001111 1010}. Parallel side DCM readings are referenced
to the TXCLK or RXCLK edge (not the data edge) that registers the K character as an input or output.
Note 13:
DCM readings are valid when the RXCLK pin on the SCAN12100 is used as an output in "WRITE" mode (RXCLKMODE = 0) and IOVDD = 3.3V.
Note 14:
Edge rate characterization includes the loading effects of 1.0 uF AC-coupling capacitors and 4 inches of 100 ohm differential microstrip.
