The third level (high-impedance state) invokes the power-down mode for standby condition. FEATURES • High frequency RF amplifiers • Power-down mode for standby condition • Suitable for all CD (785 nm) and DVD (655 nm) read/write applications Gain switch R/W is used to reduce the gain during writing. During CD-R writing with clipping, the high peak signals for the central and satellite segments are clamped internally and the output currents of the A, B, C, D, E, F, G and H segments are folded back to reduce power consumption. The output currents can be folded back to almost zero, depending on the light power detected. CD-R writing can also be done without clipping for applications where averaging is used. • Four high-bandwidth central outputs (A, B, C and D); four satellite outputs (EG, FH, ETST and HTST) and one high-bandwidth differential RF output (RFP and RFN) • Internal current clamp and current fold back (power reduction) • Versatile programmable gain switches (CD/DVD, H/L and R/W) All outputs are current outputs that can supply a maximum of 8 mA. In CD-R write clip mode, the clipping level of the output currents is between 5 mA and 8 mA. • Single 5 V supply • Current outputs for optimum signal transport over flex cable The HTSSON16T package has a low spread on the Z tolerance. The Z tolerance is measured between the diodes (chip surface) and the bottom of the leads. The diodes have an offset of 54 µm the y direction with respect to the leadframe centre and a tolerance of 50µm in both x- and y-directions. • Small outline package HTSSON16T with good positional tolerance. 2 APPLICATIONS • CD and DVD read/write applications. 3 In normal operation the satellite outputs F and H are combined as one output FH and the satellite outputs E and G are combined as one output EG. In normal mode the ETST and HTST outputs are not used (high ohmic). When pulling the R/W pin above the supply or is left open the device comes into a testing mode where all four separate satellite channels are directed to the outputs. This mode is used for Optical Pick-up Unit (OPU) alignment of the diodes where all satellite channels must be available. GENERAL DESCRIPTION The TZA1046 is a single optical pick-up IC for read/write systems and is suitable for CD and DVD applications. The device contains eight RF amplifiers for the central and satellite diodes and one differential RF amplifier (RFP and RFN) which handles the sum of the four A, B, C and D central diode signals. Programming the gain is a very versatile way to optimize interfacing between the TZA1046 and the preamplifier. The gain can be programmed for CD or DVD media with the gain switch CD/DVD. 4 ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION TZA1046TM HTSSON16T plastic thermal enhanced thin shrink small outline package/transparent; no leads; 16 terminals; body 6.6 × 5.2 × 1.1 mm 2004 May 04 3 VERSION SOT814-1 Philips Semiconductors Preliminary specification Photodiode and amplifier IC for CD and DVD applications 5 TZA1046 QUICK REFERENCE DATA SYMBOL PARAMETER CONDITIONS MIN.

In normal mode the F and H channels are combined to a single output FH and the E and G channels are combined to a single output EG. This is done to switch off two channels in the normal mode (application usage) which saves power consumption. For alignment of the diodes each individual satellite output must be available and therefore the TZA1046 can be put in a test mode where all satellite channels are available. The test mode is activated by pulling the R/W digital input pin above the supply (2 to 2.5 V higher than VDD1), by forcing an input current into this pin (800 to 1200 µA) or by leaving the pin open-circuit.

A more in-depth account of soldering ICs can be found in our “Data Handbook IC26; Integrated Circuit Packages” (document order number 9398 652 90011). • Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. • For packages with leads on two sides and a pitch (e): There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. 14.2 – larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; – smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. Reflow soldering The footprint must incorporate solder thieves at the downstream end. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. • For packages with leads on four sides, the footprint must be placed at a 45° angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical reflow peak temperatures range from 215 to 270 °C depending on solder paste material. The top-surface temperature of the packages should preferably be kept: Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 °C or 265 °C, depending on solder material applied, SnPb or Pb-free respectively. • below 225 °C (SnPb process) or below 245 °C (Pb-free process) A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. – for all BGA, HTSSON-T and SSOP-T packages 14.4 – for packages with a thickness 2.5 mm Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C. – for packages with a thickness < 2.5 mm and a volume ≥ 350 mm3 so called thick/large packages. • below 240 °C (SnPb process) or below 260 °C (Pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. Moisture sensitivity precautions, as indicated on packing, must be respected at all times. 14.3 Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. 2004 May 04 Manual soldering 20 Philips Semiconductors Preliminary specification Photodiode and amplifier IC for CD and DVD applications 14.5 TZA1046 Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE(1) WAVE REFLOW(2) BGA, HTSSON..T(3), LBGA, LFBGA, SQFP, SSOP..T(3), TFBGA, USON, VFBGA not suitable suitable DHVQFN, HBCC, HBGA, HLQFP, HSO, HSOP, HSQFP, HSSON, HTQFP, HTSSOP, HVQFN, HVSON, SMS not suitable(4) suitable PLCC(5), SO, SOJ suitable suitable not recommended(5)(6) suitable SSOP, TSSOP, VSO, VSSOP not recommended(7) suitable CWQCCN..L(8), PMFP(9), WQCCN..L(8) not suitable LQFP, QFP, TQFP not suitable Notes 1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note” (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”. 3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package body peak temperature must be kept as low as possible. 4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 5. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 6. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. The appropriate soldering profile can be provided on request. 9. Hot bar or manual soldering is suitable for PMFP packages. 15 ADDITIONAL SOLDERING INFORMATION • Reflow peak temperature for TZA1046TM should be no higher than 215 °C ± 5 °C. • Manual soldering for TZA1046TM is not encouraged. In case of touch-up desolder the defective device manually and use reflow soldering for the assembly of the replacing device. 2004 May 04 21 Philips Semiconductors Preliminary specification Photodiode and amplifier IC for CD and DVD applications TZA1046 16 DATA SHEET STATUS LEVEL DATA SHEET STATUS(1) PRODUCT STATUS(2)(3) Development DEFINITION I Objective data II Preliminary data Qualification This data sheet contains data from the preliminary specification.
