High Speed Data Receiver
Table 35 species receiver parameters measured on devices with worst case process parameters and over the full
range of operation conditions.
Table 35. External Data Input Specications
Input Data Jitter Tolerance
A receiver’s ability to tolerate incoming signal jitter is very dependent on jitter type. High speed serial interface stan-
dards have recognized the dependency on jitter type and have recently modified specifications to indicate toler-
ance levels for different jitter types as they relate to specific protocols (e.g XAUI, FC, Infiniband etc.). Sinusoidal
jitter is considered to be a worst case jitter type. Table 36 shows receiver specifications with 10 MHz sinusoidal jit-
ter injection. XAUI specic jitter tolerance measurements were measured in a separate experiment detailed in tech-
nical note TN1032, SERDES Test Chip Jitter, and are not reected in these results.

1. With PRBS 2^7-1 data pattern, all channels operating, FPGA logic active, REFCLK jitter of 30 ps., TA = 0
oC to 85oC, 1.425V to 1.575V sup-
ply.
2. Input level min + (input peak to peak swing)/2 ≤ common mode input voltage ≤ input level max - (input peak to peak swing)/2
3. The ORT42G5 and ORT82G5 SERDES receiver performs four levels of synchronization on the incoming serial data stream, providing rst
bit, then byte (character), then channel (32-bit word), and nally optional multi-channel alignment as described in TN1025. The PLL Lock
Time is the time required for the CDR PLL to lock to the transitions in the incoming high-speed serial data stream. If the PLL is unable to
lock to the serial data stream, it instead locks to REFCLK to stabilize the voltage-controlled oscillator (VCO), and periodically switches back
to the serial data stream to again attempt synchronization.
