8 / 18 page  1995 Mar 22 8 Philips Semiconductors Preliminary specification Low power VHF, UHF mixer/oscillator for TV and VCR 2-band tuners TDA5732M Notes 1. The RF signal is modulated with 50% AM at 15 kHz: The level of the RF signal is increased until there is a 23 dB difference between the LO carrier and the sideband components. 2. The frequency shift is defined as a variation in oscillator frequency when the supply voltage varies from VP = 5 to 4.75 V or from VP = 5 to 5.75 V. 3. The ripple susceptibility is measured for a 500 kHz ripple at the LO output with the set-up as illustrated in Fig.8. The level of the ripple signal is increased until there is a 53.5 dB difference between the LO carrier and the sideband components. 4. The frequency shift is defined as a variation in oscillator frequency when the supply voltage varies from Tamb =25°Cto0°C or from Tamb =25°Cto50°C. 5. The switching on drift is defined as the variation in oscillator frequency between 5 seconds and 15 minutes after switching on. 6. SRF: spurious signal on LO with respect to LO output signal; a) RF voltage level=1V at fi = 55.25 to 225 MHz. b) RF level = 2.5 dBm at fi = 225 to 361.25 MHz. c) RF level = −10 dBm at fi = 367.25 to 801.25 MHz.
