Function
(Differential) Input of 2nd IFVGA
(Differential) Input of 2nd IFVGA
Connection for time-constant capacitor of IFVGAs’ AGC
Input of IFAGC detector (differential with pin 48)
(Differential) Output of 2nd IFVGA
(Differential) Output of 2nd IFVGA
Input of IFAGC detector (differential with pin 45)
Supply voltage
Window AGC input: All AGCs frozen and currents to capacitors switched off (necessary during Null Symbol
or when unused symbols are left out and the part is powered down using the SWITCHEN input)
Input for selection between the two enable registers, allowing a fast change between reduced, low-current,
and normal-reception mode, and offering current-saving capability
Input of SPI bus (data, refer to SPI bus protocol)
Input of SPI bus (chip select, refer to SPI bus protocol)
Input of SPI bus (clock, refer to SPI bus protocol)
Output of SPI bus (data, refer to SPI 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 to 3.6V) to adaptation interface to baseband
Connection for reference clock crystal
Connection for reference clock crystal
Supply for digital circuits
