INTEGRATED CIRCUITS DATA SHEET TDA5736; TDA5737 5 V VHF, hyperband and UHF mixers/oscillators for TV and VCR 3-band tuners Product specification Supersedes data of 1996 Oct 25 File under Integrated Circuits, IC02 1997 Feb 24 Philips Semiconductors Product specification 5 V VHF, hyperband and UHF mixers/oscillators for TV and VCR 3-band tuners 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 bands B and C (balanced input) • 3-pin oscillator for band B • 4-pin oscillator for band C • Local oscillator buffer output for external prescaler • SAW filter preamplifier with a low output impedance to drive the SAW filter directly • Band gap voltage stabilizer for oscillator stability • Electronic band switch • External IF filter between the mixer output and the IF amplifier input. APPLICATIONS • 3-band all channel TV and VCR tuners • Any standard.

These low power mixer/oscillators require a power supply of 5 V and are available in a very small package. These 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.17, 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.

The limits are related to the tank circuits used in Fig.17 and the intermediate frequency. Frequency bands may be adjusted by the choice of external components. 1997 Feb 24 2 Philips Semiconductors Product specification 5 V VHF, hyperband and UHF mixers/oscillators for TV and VCR 3-band tuners ORDERING INFORMATION TYPE NUMBER TDA5736T TDA5736M TDA5737M PACKAGE NAME SO24 SSOP24 SSOP24 DESCRIPTION TDA5736; TDA5737 VERSION SOT137-1 SOT340-1 SOT340-1 plastic small outline package; 24 leads; body width 7.5 mm plastic shrink small outline package; 24 leads; body width 5.3 mm plastic shrink small outline package; 24 leads; body width 5.3 mm BLOCK DIAGRAM band A oscillator tuned cicuit handbook, full pagewidth band C oscillator tuned cicuit band B oscillator tuned cicuit GND IF outputs 23 (2) 21 (4) 24 22 20 18 (1) (3) (5) (7) 19 (6) 17 (8) 16 (9) 15 (10) 14 (11) 13 (12) BAND A OSCILLATOR BAND C OSCILLATOR BAND B OSCILLATOR TDA5736T TDA5736M TDA5737M IF AMPLIFIER MIXER MIXER MIXER ELECTRONIC BAND SWITCH LOCAL OSCILLATOR AMPLIFIER BAND A STAGE BAND C STAGE BAND B STAGE DC STABILIZER (17) 8 (16) 9 VP (15) 10 (14) 11 (13) 12 (24) (23) 1 2 (19) 6 band A input (21) 4 (20) 5 (22) 3 (18) 7 MGE971 IF filter input band C inputs RF GND band B inputs local oscillator amplifier outputs band switch input The numbers in parenthesis represent the TDA5737M.
