Function
(Differential) input of mixer for VHF
(Differential) output of mixer for VHF
Supply voltage (VCO for VHF)
Tuning voltage for integrated VCO for VHF (connected to PLL loop filter)
Ground (VCO for VHF)
Voltage outputs for frequency tuning of filters for VHF: antenna filter, pre-selection filter
Connection for "reference-tank" for generating the tuning voltages for the external VHF filters (-varactors)
(Differential) input of 2nd. IFVGA
Connection for capacitor for time constant of AGC of IF VGAs
(Differential) Output of 2nd. IFVGA
Supply voltage
"window AGC" - all AGCs "frozen" - currents to capacitors switched off - necessary during "Null Symbol" or
also during unused symbols left out and powered down using "SWITCHEN" input
Input for selection between the two "enable" registers - fast change between reduced, "low current" mode
and normal reception mode - current saving capability
Inputs and outputs of serial bus (see serial bus protocol)
Crystal oscillator clock output to baseband
if used: ac-couple to baseband (single VCXO-concept)
if not used: short-circuit to GND
Supply voltage from baseband (1.65V ... 3.6V) for adaptation of interface to baseband
Connection for crystal for reference clock
Ground
