TUA 6026

Semiconductor Group

1.2

Functional Description

The TUA 6026 device combines a digitally programmable phase locked loop (PLL), with

a mixer-oscillator block including two balanced mixers and oscillators for use in TV

tuners.

The PLL block with four hard-switched chip addresses forms a digitally programmable

phase locked loop. With a 4 MHz quartz crystal, the PLL permits precise setting of the

frequency of the tuner oscillator up to 900 MHz in increments of 62.5 kHz. The tuning

process is controlled by a microprocessor via an

2C Bus. The device has four output

ports, two of them (P0 and P1) can also be used as TTL input ports. A flag is set when

the loop is locked. The input ports and lock flag can be read by the processor via the

2C Bus.

The mixer-oscillator block includes two balanced mixers (one mixer with high-impedance

input and one mixer with a balanced low-impedance input), two frequency and

amplitude-stable balanced oscillators for VHF, HYPER and UHF, a low-noise reference

voltage source and a band switch.

1.3

Application

The IC is suitable for NTSC and PAL tuners in TV- and VCR-sets or cable set-top

receivers for analog TV and Digital Video Broadcasting.
