FUNCTIONAL DESCRIPTION Record (REC)/electric to electric (EE) mode LUMINANCE From input pin 43 the CVBS signal is fed via the automatic gain control (AGC) and subclamp (SCL) to the output pin 41. Instead of the controlled and clamped CVBS signal it is also possible to switch (dependent on the level at pin 42) white, black or sync-level to this pin. To eliminate chrominance parts the CVBS signal is fed to the luminance low-pass filter (YLPF) and to the sync separator stage. The sync signal is available at pin 45. The signal is also fed via vertical emphasis non-linear emphasis (NLE), deviation control stage, main emphasis and white-dark clip to the FM modulator. The FM signal is available at pin 11. CHROMINANCE The chrominance signal is selected out of CVBS (from pin 43) in BPF 4.43 MHz (band-pass filter) and controlled in automatic chrominance control (ACC). The chrominance signal is mixed with 5.06 MHz to 627 kHz and via LPF 627 kHz to the output pin 30.
TDA9725
Playback (PB)/video to video (VV) mode LUMINANCE The FM signal is fed via FM AGC and double limiter to the controlled FM demodulator. After demodulation and filtering in sub low-pass filter (SUBLPF) main de-emphasis, YLPF and non-linear de-emphasis the signal is fed to the vertical noise reduction (YNR) and in parallel to the sync separator. The chrominance signal is added in the Y/C mixer. The complete CVBS signal is available at pin 41. CHROMINANCE The 627 kHz chrominance signal coming from tape via BPF 627 kHz and field ACC to the balanced mixer. Mixed with 5.06 MHz the 4.43 MHz chrominance signal is fed via comb driver stage to the external comb filter (pin 35) and via internal conjugated complex (C*) stage and internal AC coupling to the luminance part. Record and playback In both modes record (REC) and playback (PB) the 5.06 MHz mixer frequency is produced by the 20.24 MHz voltage controlled oscillator (VCO) and a divide-by-four.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values
TDA9725
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified storage maximum (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds.
This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.
