CBTU0808 Dual lane PCI Express port multiplexer Rev. 01 — 2 June 2006 Product data sheet 1. General description The CBTU0808 is a dual lane port multiplexer designed to provide convenient and reliable path switching for PCI Express signals. It is organized as two PCI Express lanes, each consisting of a Transmit and Receive channel. Each channel has four ports, two (A and B) on the source (or host) side and two (A and B) on the destination (or device) side. Each port provides a pair of signal lines to support PCIe differential signaling. Using specially designed high-bandwidth and high off-isolation switch elements, source and destination ports can be connected or isolated in three possible configurations: source A and B to destinations A and B respectively; or source A to destination B (remaining ports isolated), or all ports isolated. The switch elements are controlled by internal control logic to set switch positions in accordance with these three configurations, selectable by CMOS inputs CTRL0 and CTRL1 for lanes 0 and 1 respectively. Within a lane, the switch configuration is always applied identically to both transmit and receive channels. The CBTU0808 is packaged in a 48-ball, depopulated 9 × 9 grid, 0.5 mm ball pitch, thin profile fine-pitch ball grid array (TFBGA) package, which (while requiring a minimum 5 mm × 5 mm of board space) allows for adequate signal routing and escape using conventional board technology. 2.

Functional description 7.1 Functional description 7.1.1 General information The CBTU0808 Dual lane PCI Express port multiplexer is designed to allow port switching of up to two PCI Express lanes (each including a Transmit and Receive channel) according to three switch configuration settings (described in Section 7.1.2.1). The basic switch element of the CBTU0808 is designed integrally with its package and chip interconnect to present an optimum characteristic on-impedance when used in a PCI Express signaling environment, and to provide high off-port isolation and low crosstalk. 7.1.2 Functional information The following paragraphs describe the control and configuration possibilities available in the CBTU0808. 7.1.2.1 Switch configuration The position of the port switches is controlled by CMOS input signals CTRL[1:0] and can be overridden by CMOS input TEST0 to disconnect (open) all ports between source and destination. For a given lane, the switch positions are always identical between transmit and receive channels. Lane 0 is controlled by CTRL0 and Lane 1 is controlled by CTRL1. The truth table for the switch position as a function of these inputs is shown in Table 3. Table 3.

Soldering 14.1 Introduction to soldering surface mount packages 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 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. 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 seconds and 200 seconds depending on heating method. Typical reflow temperatures range from 215 °C to 260 °C depending on solder paste material. The peak top-surface temperature of the packages should be kept below: Table 8. SnPb eutectic process - package peak reflow temperatures (from J-STD-020C July 2004) Package thickness Volume mm3 < 350 Volume mm3 ≥ 350 < 2.5 mm 240 °C + 0/−5 °C 225 °C + 0/−5 °C ≥ 2.5 mm 225 °C + 0/−5 °C 225 °C + 0/−5 °C Table 9. Pb-free process - package peak reflow temperatures (from J-STD-020C July 2004) Package thickness Volume mm3 < 350 Volume mm3 350 to 2000 Volume mm3 > 2000 < 1.6 mm 260 °C + 0 °C 260 °C + 0 °C 260 °C + 0 °C 1.6 mm to 2.5 mm 260 °C + 0 °C 250 °C + 0 °C 245 °C + 0 °C ≥ 2.5 mm 250 °C + 0 °C 245 °C + 0 °C 245 °C + 0 °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. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: • 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): CBTU0808_1 Product data sheet © Koninklijke Philips Electronics N.V. 2006. All rights reserved. Rev. 01 — 2 June 2006 12 of 16 CBTU0808 Philips Semiconductors Dual lane PCI Express port multiplexer – 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. 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. 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 dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 °C or 265 °C, depending on solder material applied, SnPb or Pb-free respectively. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 14.4 Manual soldering 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. When using a dedicated tool, all other leads can be soldered in one operation within 2 seconds to 5 seconds between 270 °C and 320 °C. 14.5 Package related soldering information Table 10.

[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.

Rev. 01 — 2 June 2006 13 of 16 CBTU0808 Philips Semiconductors Dual lane PCI Express port multiplexer [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, QFP and TQFP 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 soldering or manual soldering is suitable for PMFP packages. 15. Abbreviations Table 11.
