Figure 18. Test Modes
SQUELCH MODE
When the squelch input is driven to a TTL high state, both the
clock and data outputs are set to the zero state to suppress
downstream processing. If desired, this pin can be directly
driven by the LOS detector output, SDOUT. If the squelch
function is not required, the pin should be tied to VEE.
TEST MODES: BYPASS AND LOOPBACK
When the bypass input is driven to a TTL high state, the
quantizer output is connected directly to the buffers driving the
data out pins, thus bypassing the clock recovery circuit (see
Figure 18). This feature can help the system deal with
nonstandard bit rates.
The loopback mode can be invoked by driving the LOOPEN
pin to a TTL high state, which facilitates system diagnostic
testing. This connects the test inputs (TDINP/N) to the clock
and data recovery circuit (per Figure 18). The test inputs have
internal 50 terminations and can be left floating when not in
use. TDINP/N are CML inputs and can only be dc-coupled
when being driven by CML outputs. The TDINP/N inputs must
be ac-coupled if being driven by anything other than CML
outputs. Bypass and loopback modes are mutually exclusive.
Only one of these modes can be used at any given time. The
ADN2811 is put into an indeterminate state if the BYPASS and
LOOPEN pins are set to Logic 1 at the same time.
