Function
This pin should be connected to the 27 MHz crystal or left as a no connect if an external
3.3 V, 27 MHz clock oscillator source is used to clock the ADV7181. In crystal mode, the
crystal must be a fundamental crystal.
A logic low on this pin places the ADV7181 in a power-down mode. Refer to the I2C Control
Register Map section for more options on power-down modes for the ADV7181.
The recommended external loop filter must be connected to this ELPF pin, as shown in
Figure 42.
Subcarrier Frequency Lock. This pin contains a serial output stream that can be used to lock
the subcarrier frequency when this decoder is connected to any Analog Devices digital
video encoder.
Internal Voltage Reference Output. Refer to Figure 42 for a recommended capacitor
network for this pin.
Common-Mode Level for the Internal ADCs. Refer to Figure 42 for a recommended
capacitor network for this pin.
ADC’s Capacitor Network. Refer to Figure 42 for a recommended capacitor network for
this pin.
