Mode Recovery Timing
Figure 6 shows the mode recovery timing diagram.
tWAKE is the wake-up time when exiting shutdown, idle,
or standby mode and entering into Rx, Tx, or Xcvr
mode. tENABLE is the recovery time when switching
between any Rx, Tx, or Xcvr mode. tWAKE or tENABLE is
the time for the ADC to settle within 1dB of specified
SINAD performance and DAC settling to 10 LSB error.
tWAKE or tENABLE times are measured after the 8-bit
serial command is latched into the MAX5865 by CS
transition high. tENABLE for Xcvr mode is dominated by
the DAC wake-up time. The recovery time is 10s to
switch between Xcvr, Tx, or Rx modes. The recovery
time is 40s to switch from shutdown or standby mode
to Xcvr mode.
System Clock Input (CLK)
CLK input is shared by both the ADCs and DACs. It
accepts a CMOS-compatible signal level set by OVDD
from 1.8V to VDD. Since the interstage conversion of the
device depends on the repeatability of the rising and
falling edges of the external clock, use a clock with low
jitter and fast rise and fall times (<2ns). Specifically,
sampling occurs on the rising edge of the clock signal,
requiring this edge to provide the lowest possible jitter.
Any significant clock jitter limits the SNR performance
of the on-chip ADCs as follows:
where fIN represents the analog input frequency and
tAJ is the time of the clock jitter.
