INTEGRATED CIRCUITS DATA SHEET TZA1045 Photodiode and amplifier IC for CD and DVD applications Preliminary specification Supersedes data of 2002 Nov 27 2003 Jun 26 Philips Semiconductors Preliminary specification Photodiode and amplifier IC for CD and DVD applications TZA1045 FEATURES 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. • High frequency RF amplifiers (typical bandwidth = 240 MHz) • Suitable for all CD (785 nm) and DVD (655 nm) read/write applications Programming the gain is a very versatile way to optimize interfacing between the TZA1045 and the pre-amplifier. The gain can be programmed for CD or DVD media with the gain switch CD/DVD. • Four high bandwidth central outputs (A, B, C, and D), four satellite outputs (E, F, G, and H) and one high bandwidth differential output (RFP, RFN) The H/L switch can be used for CD-R or CD-RW discs. • Internal current clamp and current fold back (power reduction) Gain switch R/W is used to reduce the gain during writing. During writing, 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 reduced to almost zero (fold back) to minimize the power consumption. • Versatile programmable gain switches (CD/DVD, H/L, and R/W) • Single 5 V supply • Current outputs for optimum signal transport over flex cable All outputs are current outputs that can supply a maximum of 8 mA. In CD-R writing mode, the clipping level of the output currents is between 5 and 8 mA. • Small outline package SSOP16T with good positional tolerance. GENERAL DESCRIPTION The SSOP16T 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 in the ‘y’ direction with respect to the leadframe centre and a tolerance of ±50 µm in both ‘x’ and ‘y’ directions. The TZA1045 is a single optical pick-up IC for read/write systems and is suitable for CD and DVD applications. The diodes are placed under an angle of 45° ±1° with respect to the leadframe of the module. APPLICATIONS • CD and DVD read/write applications.

SOLDERING Introduction to soldering surface mount packages If wave soldering is used the following conditions must be observed for optimal results: This text gives a very brief insight to a complex technology. 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. 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. • For packages with leads on two sides and a pitch (e): – 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 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. The footprint must incorporate solder thieves at the downstream end. • 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 220 °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 and SSOP-T packages – for packages with a thickness ≥ 2.5 mm Manual soldering – for packages with a thickness < 2.5 mm and a volume ≥ 350 mm3 so called thick/large packages. 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. • below 235 °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. 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. 2003 Jun 26 16 Philips Semiconductors Preliminary specification Photodiode and amplifier IC for CD and DVD applications TZA1045 Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE(1) WAVE BGA, LBGA, LFBGA, SQFP, SSOP-T(3), TFBGA, VFBGA not suitable suitable(4) DHVQFN, HBCC, HBGA, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, HVSON, SMS not PLCC(5), SO, SOJ suitable LQFP, QFP, TQFP SSOP, TSSOP, VSO, VSSOP REFLOW(2) suitable suitable suitable not recommended(5)(6) suitable not recommended(7) 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. 2003 Jun 26 17 Philips Semiconductors Preliminary specification Photodiode and amplifier IC for CD and DVD applications TZA1045 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.
