FUNCTION
High-Frequency RF Input. Matched to 75 I over the operating band. Requires a DC-blocking capacitor.
RF Ground. Bypass to the PCB’s ground plane with a 1000pF capacitor. Keep traces as short as
possible to minimize inductance to ground plane. Do not connect RFGND1 and RFGND2 together.
RF VGA Gain Control Voltage. Accepts a DC voltage from 0.5V to 3V.
IF Power Supply. Requires a 600 I series ferrite bead to a bypass capacitor to ground.
RF Ground. Bypass to the PCB’s ground plane with a 1000pF capacitor. Keep traces as short as
possible to minimize inductance to ground plane. Do not connect RFGND1 and RFGND2 together.
Dual-Mode DTV IF Output. In single-ended mode, this pin is the IF signal output. In differential mode, this
pin is the positive terminal of the differential IF output.
Dual-Mode DTV IF Output. In single-ended mode, this pin is the SAW filter bandwidth switch. In
differential mode, this pin is the negative terminal of the differential IF output.
IF VGA Gain Control Voltage. Accepts a DC voltage from 0.5V to 3V.
2-Wire Serial-Interface Address Line. This pin sets the device address for the I 2 C-compatible serial
interface. There are three selectable addresses based on the state of this pin: logic-low, logic-high, or
unconnected.

Ground. Connect pin to paddle ground to minimize trace inductance.
Power-Supply Connections. Bypass each supply pin with a separate 1000pF capacitor to ground.
Single-Ended IF Output. Connect to the analog demodulator input. Requires a 1000pF DC-blocking
capacitor.
Differential IF VGA Output. Connect to the demodulator input. Requires a 1000pF DC-blocking capacitor.
Crystal Output to Drive Baseband IC. Output frequency is f XTAL or f XTAL /4.
Digital Supply. Requires a 15 I series resistor to a 1 F F bypass capacitor.
2-Wire Serial Clock Interface. Connect to the serial bus and ensure the bus includes an approximately
5k I pullup resistor.
Crystal Oscillator Base. Connect to the crystal through a DC-blocking capacitor and connect a capacitor
to XTALE.
Crystal Oscillator Emitter. Connect a capacitor to ground and a capacitor to XTALB.
Reference Frequency Divider Control. Three modes are available depending on the state of this pin:
high = f XTAL /1, low = f XTAL /4, unconnected = state determined by register. Note: Power-up state of
register is not guaranteed; therefore, unconnected mode should only be used if the controller can
reprogram I 2 C in any of the divider settings.
2-Wire Serial Data Interface. Connect to serial bus and ensure the bus includes an approximately 5k I
pullup resistor.
PLL Charge-Pump Output and TUNE Input. Connect to the PLL loop filter.
Bypass for On-Chip VCO LDO. Bypass to ground with a 0.47 F F capacitor.
