Philips Semiconductors
9 V VHF, hyperband and UHF
mixer/oscillator for TV and VCR 3-band tuners
Product specification
TDA5630;
TDA5631
FEATURES
• Balanced mixer with a common emitter input for band A
(single input)
• 2-pin oscillator for bands A and B
• Balanced mixer with a common base input for
bands B and C (balanced input)
• 3-pin oscillator for band C
• Local oscillator buffer output for external synthesizer
• SAW filter preamplifier with a low output impedance to
drive the SAW filter directly
• Band gap voltage stabilizer for oscillator stability
• Electronic band switch.
APPLICATIONS
• 3-band all channel TV and VCR tuners
• Any standard.
GENERAL DESCRIPTION
The TDA5630 and TDA5631 are monolithic integrated
circuits that perform the mixer/oscillator functions for
bands A, B and C in TV and VCR tuners. These low-power
mixer/oscillators require a power supply of 9 V and are
available in a very small package.
The devices give the designer the capability to design an
economical and physically small 3-band tuner.
They are suitable for European standards, as illustrated in
Fig.12, with the following RF bands: 48.25 to 168.25 MHz,
175.25 to 447.25 MHz and 455.25 to 855.25 MHz. With
an appropriate tuned circuit, they are also suitable for
NTSC all channel tuners (USA and Japan).
The tuner development time can be drastically reduced by
using these devices.

1. The limits are related to the tank circuits used in Fig.12 and the intermediate frequency. Frequency bands may be
adjusted by the choice of external components.
