N1076A Electrical Clock Recovery
The N1076A provides instrument-grade clock recovery on electrical signals from 50 MBaud up
to 32 GBaud (32.8 GBaud characteristic). Adjustable loop bandwidth (to 20 MHz) and peaking
ensures standards-compliant clock recovery capability. The N1076A is controlled via a USB
connection to an 86100D DCA-X mainframe, or to a standalone PC running N1010A FlexDCA
software.

Figure 5. As shown in this block diagram of the electrical clock recovery, the N1076A recovers clock signals
from NRZ and PAM4 input signals, and provides jitter analysis capability (Option JSA) for additional insight
and measurement accuracy.
Accurate clock recovery for high-speed applications
–– Recovers clock from data streams up to 32 GBaud (Option 232) and 16 GBaud
(Option 216)
–– Supports both NRZ and PAM4 signal types
–– Tolerates small input signals with input sensitivity as low as 40 mVpp differential, or
20 mVpp single-ended
–– Provides an auxiliary clock output signal with intrinsic random jitter as low as
100 fs RMS for accurate measurements. Use to connect to 86100D DCA-X precision
timebase (PTB) input
–– Optional jitter spectrum analysis (Option JSA) feature provides additional insight into
jitter and allows users to perform jitter measurements using an “ideal” clock recovery
model
–– Connects to an 86100D DCA-X or PC via a USB 2.0 interface
