(see fig.1) is capable of locking onto the video signal thereby implementing a horizontal gate signal href (href = high when data is valid) and a vs signal indicating the start of a new video frame. this module expects, in the pal mode, 288 active lines from a total of 292 lines and in the vga mode, 480 active lines from a total of 486 lines. the module generates control signals for the cif formatter. 8.2 cif formatter the video data must be progressive (or non-interlaced) and in 4 :2:2 (uyvy) format. the cif formatter module (see figs 1 and 3) is programmable to perform down scaling from 512 288 (pal mode) or 640 480 (vga mode) to 352 288 or 176 144 without affecting the aspect ratio. the horizontal scaling is achieved with a variable phase delay filter (vpd-4). to avoid aliasing, this module also contains a prefilter which has three modes: prefilter a (3 taps) prefilter b (7 taps) prefilter b-comb (13 taps). prefilter b-comb is similar to prefilter b, but inserts extra taps with amplification 0. this prefilter must be chosen by selecting prefilter b and setting sn_prefilter_b_comb. prefilter b-comb can be used independently from prefilter a. the incoming 4:2:2 data is vertically filtered to 4 : 2 : 0 by throwing away colour samples. in the even lines the v-samples are discarded, in the odd lines the u-samples. the vertical scaling in pal mode is from cif (352 288) to qcif (176 144) only. this is done via a vertical prefilter a (3 taps). in vga mode a vpd-4 vertical filter is applied to scale from 640 480 to cif and qcif. from the qcif image a sub-qcif cut (128 96) can be made. due to the granularity of the cropping origin, a uv interchange can occur. this interchange can be corrected with sn_eirrah. in vga mode the cif formatter can be bypassed to create a full resolution snapshot. the snapshot can be in 4 :2:0 and in 4 :2:2 format, selectable with sn_4 :2:2. 8.3 compression engine the compression engine module (see figs 1 and 3) works on cif format only. the cif data is compressed to a fixed number of bytes per frame. this number can be selected leading a compression factor of either 3 or 4. as a result the data stream of ci f4:2:0 equals the data stream of qcif 4:2:2 (3 times compression) or qcif 4:2:0 (4 times compression). the algorithm is philips proprietary. real-time decoding can be done in software on any pentium platform. fig.3

digital camera usb interface ic saa8117hl 8.4 transfer buffer the transfer buffer module (see fig.1) ensures a smooth transfer of the data to the fifo of the usb. moreover the transfer buffer can insert in band synchronization words in the video data stream. this function can be switched on and off with sn_in band_control in register control17_0. the synchronization words can only be used with non-compressed data streams and are formatted like 0x00 0xff 0x 1999 apr 02 12 philips semiconductors product speci?cation digital camera usb interface ic saa8117hl this text is here in white to force

speci?cation digital camera usb interface ic saa8117hl 8.8 usb video fifo the usb video fifo is programmed via the i 2 c-bus (see fig.22). the fifo is designed to achieve three different packets containing video on the isochronous usb channel. video data is contained in a chain of equally sized usb packets, except for the last packet of a video frame which is always smaller. the video frames can be separated from each other by one or more 0-length packets. for low frame rates (below 10 frames/s) there are always 0-length packets in the stream. the host can synchronize on the smaller packets for the high frame rates and on the 0-length packets for the low frame rates. for every mode the fifo must be adjusted. there are three parameters to program the video fifo: i 2 c_packet_size: this value indicates the length of all packets with video data except for the last packet of a video frame i 2 c_fifo_offset: this value indicates the number of data in the fifo before a new packet is transmitted over the usb i 2 c_read_spacing: this value indicates the number of 12 mhz clock cycles between read actions from the fifo. moreover the fifo is enabled and disabled with i 2 c_active. the write process to the fifo is controlled by the transfer buffer and is not programmable. the read process is executed in the psie-mmu and is driven by the usb frame interval (1 ms). every frame interval the psie-mmu tries to read i 2 c_packet_size bytes from the fifo. this read process will not be started when a new video frame is stored in the fifo and there are less than i 2 c_fifo_offset bytes written. the read process stops if the next bytes are of another video frame, or if the read-pointer overtakes the write-pointer. i 2 c_read_spacing determines the read rate. its value can easily be determined with the formula: i 2 c_read_spacing 12000 i 2 c_packet_size --------------------------------------------- < fig.22 usb video fifo. handbook, full pagewidth write sync fifo

product speci?cation digital camera usb interface ic saa8117hl 8.9 psie-mmu, i 2 c-bus interface and usb ram space the programmable serial interface engine (psie) and memory management unit (mmu) is the heart of the usb protocol hardware (see fig.23). it formats the actual packets that are transferred to the usb and passes the incoming packets to the right end-point buffers. these buffers are allocated as part of the usb ram space. the microcontroller communicates via the i 2 c-bus with the psie-mmu. the i 2 c-bus protocol distinguishes three register spaces. these spaces are addressed via different commands. the command is sent to the command address. depending on the command it is sent to the psie-mmu and/or to the command interpreter which configures the (de-)mux to open the path to the right register space. subsequent write/read to/from the data address store or retrieve data from the register space is selected by the command. 8.10 atx and external atx interface the saa8117hl contains an analog bus driver, called the atx. it incorporates a differential and two single-ended receivers and a differential transmitter. the interface to the bus consists of a differential data pair (atxdm and atxdp). the saa8117hl contains also an interface to an external atx as backup solution. fig.23 i 2 c-bus interface and register map. handbook, full pagewidth pi_address + 0x pi_address

semiconductors product speci?cation digital camera usb interface ic saa8117hl 8.11 audio the pll converts the 48 mhz to 256f s (f s = audio sample frequency). there are three modes for the pll to achieve the sample frequencies of 48, 44.1 or 32 khz (see table 1). in the fixed gain amplifier (fga) the microphone input is amplified by 20 db. the bit stream adc samples the audio signal. it runs at an oversample rate of 256 times the base sample rate. in the application, the bit stream can be converted to parallel 16-bit samples. this conversion is programmable with respect to the effective sample frequency (dropping sample results in a lower effective sample frequency) and sample resolution. as a result the effective sample rate can be determined. table 1 adc clock frequencies and sample frequencies note 1. not supported. clock (mhz) dividing number sample frequency (khz) adc clock (mhz) 8.1920 1 32 4.096 2 16 2.048 4 8 1.042 8 note 1 note 1 11.2996 1 44.1 5.6448 2 22.05 2.8224

module since the device may not consume more than 500 m a during the power state called suspend. this requires that even the crystal oscillator must be switched off. the saa8117hl is also not functional except for some logic that enables the ic to wake-up the camera. after wake-up of the saa8117hl first the clock to the microcontroller is generated and thereafter an interrupt is generated to wake-up the controller. therefore the clock of the microcontroller is generated by the saa8117hl. the power management module also sets a flag in register i 2 c_set_mode_and_read. after a reset the microcontroller should check this register via the i 2 c-bus and find the cause of the wake-up. different causes may require different start-up routines. the internal video processing core uses another v ddd domain which can be switched during suspend. the ppg is switched off by setting sn_resume and resetting sn_pal_vga. in non cif modes the power consumption is reduced by resetting sn_compress and sn_clk_compress_on. the saa8117hl has the feature to independently wake-up from suspend, but requires a signal from the microcontroller before going into suspend (via the signal on pin susreadynot). since the main oscillator of the saa8117hl is switched off during suspend precautions are needed to avoid undefined states when the clock is switched on. this is ensured via the pins clockon and trc. pin clockon goes high as soon as the main oscillator is switched on. the oscillator will need some time to make a stable 48 mhz signal. however, the clock is only passed through to other parts of the saa8117hl when the level on pin trc reaches a certain threshold. the time needed to reach the threshold can be trimmed with an rc-circuit. 1999 apr 02 33 philips semiconductors

speci?cation digital camera usb interface ic saa8117hl 16 soldering 16.1 introduction to soldering surface mount packages 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). there is no soldering method that is ideal for all surface mount ic packages. wave soldering is not always suitable for surface mount ics, or for printed-circuit boards with high population densities. in these situations reflow soldering is often used. 16.2 re?ow 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. several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 250 c. the top-surface temperature of the packages should preferable be kept below 230 c. 16.3 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): C 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; C 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 is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 16.4 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 to 5 seconds between 270 and 320 c. 1999 apr 02 56 philips semiconductors product speci?cation digital camera usb interface ic saa8117hl 16.5 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. 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 . 2. these packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. 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. 4. wave soldering is only suitable for lqfp, tqfp and qfp packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. wave soldering is only suitable for ssop and tssop 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.
