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).
FEATURES
• Single-chip 5 V mixer/oscillator and synthesizer for cable TV and VCR tuners
• Pin-to-pin compatible with TDA6402, TDA6402A, TDA6403 and TDA6403A
• Universal bus protocol (I2C-bus or 3-wire bus):
– Bus protocol for 18 or 19-bit transmission (3-wire bus)
– Extra protocol for 27-bit transmission (test modes and features for 3-wire bus)
– Address + 4 data bytes transmission (I2C-bus ‘write’ mode)
– Address + 1 status byte (I2C-bus ‘read’ mode)
– 4 independent I2C-bus addresses.
• 1 PMOS buffer for UHF band selection (25 mA)
• 3 PMOS buffers for general purpose, e.g. 2 VHF sub-bands, FM sound trap (25 mA)
• 33 V tuning voltage output
• In-lock detector
• 5-step analog-to-digital converter (3 bits in I2C-bus mode)
• 15-bit programmable divider
• Programmable reference divider ratio (64, 80 or 128)
• Programmable charge pump current (60 or 280µA)
• Varicap drive disable
• Balanced mixer with a common emitter input for VHF(single input)
• Balanced mixer with a common base input for UHF(balanced input)
• 2-pin common emitter oscillator for VHF
• 4-pin common emitter oscillator for UHF
• IF preamplifier with asymmetrical 75Ω output impedance able to drive loads from 75 Ωupwards
• Low power
• Low radiation
• Small size
• The TDA6502A and TDA6503A differ from the TDA6502 and TDA6503 by the UHF port protocol in the I2C-bus mode (see Tables 3 and 4).APPLICATIONS
• Cable tuners for TV and VCR (switched concept for VHF).
