L64733/L64734 Tuner and Satellite Receiver Chipset

9

The following signal descriptions are listed according to the major

interface groups. Within each group, the signals are described in

alphabetic order.

RF Signals

The L64733 can accept an RF input signal and loop it through to RFOUT.

This is controlled by an on-chip RF switch.

RFINn, RFINp RF Input

Input

The RFIN differential signals form the 75

Ω input.

Connect the RFINp signal through a series 100 pF

capacitor to a 75

Ω F video connector and the RFINn

signal through a series 75

Ω resistor and 100 pF

capacitor to ground.

RFOUT

RF Output

Output

The RFOUT signal is a 75

Ω output that is active when

the INSEL input is deasserted. When active, the signal at

RFOUT is a copy of the RFIN signal.

Oscillator Signals

The L64733 has two internal oscillators: a crystal oscillator and a tank

oscillator.

CFLT

Bias Voltage Bypass

Bidirectional

See Figure 7 on page 22 for information on how to

connect the CFLT pin.

TANKn, TANKp

Oscillator Tank Port

Input

See Figure 7 on page 22 for information on how to

connect the TANKp and TANKn pins.

VRLO

Local Oscillator Regulator Bypass

Bidirectional

See Figure 7 on page 22 for information on how to

connect the VRLO pin.

XTLn, XTLp

Crystal Oscillator Port

Input

Connect the XTLp and XTLn pins as shown in Figure 7

on page 22.
