GENERAL DESCRIPTION

The TDA6502, TDA6502A, TDA6503 and TDA6503A are

programmable 2-band mixers/oscillators and synthesizers

intended for VHF/UHF TV and VCR tuners (see Fig.1).

Partitioning of the bands is up to the customer as long as

VHF is below 500 MHz and UHF is below 900 MHz.

The devices include two double balanced mixers and two

oscillators for the VHF and UHF band respectively, an

IF amplifier and a PLL synthesizer. The VHF band can be

split-up into two sub-bands using a proper oscillator

application and a switchable inductor.

Two pins are available between the mixer output and the

IF amplifier input to enable IF filtering for improved signal

handling.

The port register provides four PMOS ports. Band

selection is provided by port register UHF. When port

the VHF band is switched off. When port register UHF is

‘off’, the VHF mixer-oscillator is active and the UHF band

is off. Port registers VHFL and VHFH are used to select

the VHF sub-bands. Port register FMST is a general

purpose port, that can be used to switch an FM sound trap.

When the ports are used, the sum of the drain currents has

to be limited to 30 mA.

The synthesizer consists of a 15-bit programmable divider,

a crystal oscillator and its programmable reference divider

and a phase comparator (phase/frequency detector)

combined with a charge pump which drives the tuning

amplifier, including the 33 V output at pin VT. Depending

on the reference divider ratio (64, 80 or 128), the phase

comparator operates at 62.5, 50 or 31.25 kHz with a

4 MHz crystal.

Depending on the voltage applied to pin SW (see Table 2)

the device is operating in the I

C-bus mode or 3-wire bus

mode.

In the 3-wire bus mode, pin LOCK/ADC is the ‘lock’ output

of the PLL and is at LOW level when the PLL is locked.

Lock detector bit FL of the status byte is set to logic 1 when

the loop is locked and is read on the SDA line during a

READ operation in I

C-bus mode only.

In the I

C-bus mode only, pin LOCK/ADC is the ADC input

for digital AFC control. The ADC code is read during a

READ operation on the I

C-bus.

In the test mode, in both I

C-bus mode and 3-wire bus

mode, pin LOCK/ADC is used as a test output for f

3-wire bus format

Data is transmitted to the device during a HIGH level on

pin CE/AS (enable line). The device is accessible with

18-bit and 19-bit data formats (see Figs 4 and 5). The first

four bits are used to program the PMOS ports and the

remaining bits control the programmable divider. A 27-bit

data format (see Fig.6) may also be used to set the charge

pump current, the reference divider ratio and the test

modes.

It is not allowed to address the device with words whose

length is different from 18, 19 or 27 bits.

Note

Five serial bytes (including the address byte) are required

to address the device, select the VCO frequency, program

the four ports, set the charge pump current and set the

reference divider ratio. The device has four independent

C-bus addresses which can be selected by applying a

specific voltage to pin CE/AS.

1. The selection of the reference divider is given by an

automatic identification of the data word length. When

the 27-bit format is used, the reference divider is

controlled by bits RSA and RSB (see Table 8). More

details are given in Section 8.3.
