dBm
–1.68 dB.
2. Verified with PRBS7 pattern, electrical inputs > 150 mVp-p and optical inputs > 3 dB above specification for minimum input level to acquire lock. Output jitter
verification results of the 83496B can be affected by jitter on the input test signal. The 83496B will track jitter frequencies inside the loop bandwidth, and the jitter will
appear on the recovered clock output. Vertical noise (such as laser RIN) on the input signal will be converted to jitter by the limit amplifier stage on the input of the clock
recovery. These effects can be reduced by lowering the Loop bandwidth setting.
3. At rates below 1 Gb/s, loop bandwidth is fixed at 30 KHz when Option 300 is not installed.
4. Without Option 200 loop bandwidth is adjustable from 15 KHz to 6 MHz. Available loop bandwidth settings also depend on the data rate of the input signal. For transi-
tion density from 0.25 to 1, the Loop Bandwidth vs Rate chart shows available loop bandwidth settings. Higher loop bandwidths can be achieved when average data
transition density is maintained at or above 50%.
