ADV7403
Pin No. Mnemonic Type Function
mode the crystal must be a fundamental crystal.
46 ELPF O The recommend external loop filter must be connected to this
ELPF pin.
70, 59 TEST0 -
TEST1 O These pins should be unconnected
15 SFL/SYNC_O
UT
O SFL (Subcarrier Frequency Lock); this pin contains a serial
output stream which can be used to lock the subcarrier
frequency when this decoder is connected to any Analog
Devices digital video encoder. SYNC_OUT is the sliced sync
output signal only available in CP mode.
64 REFOUT O Internal voltage reference output.
65 CML O The CML pin is a common-mode level for the internal ADCs.
61, 62 CAPY1–
CAPY2 I ADC capacitor network.
68, 69 CAPC1–
CAPC2 I ADC capacitor network.
67 BIAS O BIAS is an external bias setting pin. Connect the
recommended resistor between pin and ground.
86 HS_IN/CS_IN I Can be configured in CP mode to be either a digital HS input
signal or a digital CS input signal used to extract timing in a
5-wire or 4-wire RGB mode.
85 VS_IN I VS input signal used in CP mode for 5-wire timing mode.
79 DE_IN I DE_IN is a data enable input signal used in 24-bit digital
input port mode, for example,
24-bit RGB data from a DVI Rx IC.
35 DCLK_IN I DCLK_IN is a clock input signal used in 24-bit digital input
mode (e.g. 24-bit RGB data from a DVI Rx IC) and also in
digital CVBS input mode.
52 SOG I SOG is a sync on green input used in embedded sync mode.
77 SOY I SOY is a sync on luma input used in embedded sync mode.
