Philips Semiconductors
9 V VHF and UHF mixer/oscillator for TV
and VCR cable tuners
Product specification
TDA5630BT
FEATURES
• Balanced mixer with a common emitter input for band A
(single input)
• 2-pin oscillator for band A
• Balanced mixer with a common base input for band C
• 3-pin oscillator for band C
• Local oscillator buffer output for external prescaler
• SAW filter preamplifier with a low output impedance to
drive a SAW filter
• Band gap voltage stabilizer for oscillator stability
• Electronic band switch.
APPLICATIONS
• Cable tuners for TV and VCR
(switched concept for VHF)
• Recommended RF bands for Europe:
48.25 to 105.25 MHz, 112.25 to 294.25 MHz and
471.25 to 855.25 MHz
• Recommended RF bands for the USA:
55.25 to 133.25 MHz, 139.25 to 361.25 MHz and
367.25 to 801.25 MHz.
GENERAL DESCRIPTION
The TDA5630BT is a monolithic integrated circuit that
performs VHF and UHF mixer/oscillator functions in TV
and VCR cable tuners. With a proper oscillator application
and by using a switchable inductor to split the VHF band
into two sub-bands, the full VHF/UHF TV bands can be
covered. This low-power mixer/oscillator requires a power
supply of 9 V and is available in a very small package.
The device gives the designer the capability to design an
economical and physically small cable tuner.
The tuner development time can be drastically reduced by
using this device.
Frequency bands are determined by the external tank
circuit. They can be adapted to various standards.
