GS1531 HD-LINX® II Multi-Rate Serializer with ClockCleaner™ GS1531 Data Sheet Key Features • SMPTE 292M and SMPTE 259M-C compliant scrambling and NRZ → NRZI encoding (with bypass) DVB-ASI sync word insertion and 8b/10b encoding Rejection of more than 300ps jitter on the input PCLK User selectable additional processing features including: • • • • • • • • • • • • CRC, ANC data checksum, and line number calculation and insertion TRS and EDH packet generation and insertion illegal code remapping Description The GS1531 is a multi-standard serializer with an integrated cable driver. When used in conjunction with the GO1555/GO1525* Voltage Controlled Oscillator, a transmit solution can be realized for HD-SDI, SD-SDI and DVB-ASI applications. The device features an internal PLL, which can be configured for loop bandwidth as narrow as 100kHz. Thus the GS1531 can tolerate in excess of 300ps jitter on the input PCLK and still provide output jitter well within SMPTE specification. Connect the output clocks from Gennum’s GS4911 clock generator directly to the GS1531’s PCLK input and configure the GS1531’s loop bandwidth accordingly. In addition to serializing the input, the GS1531 performs NRZ-to-NRZI encoding and scrambling as per SMPTE 292M/259M-C when operating in SMPTE mode. When operating in DVB-ASI mode, the device will insert K28.5 sync characters and 8b/10b encode the data prior to serialization. Parallel data inputs are provided for 10-bit multiplexed or 20-bit demultiplexed formats at both HD and SD signal rates. An appropriate parallel clock input signal is also required. The integrated cable driver features an output mute on loss of parallel clock, high impedance mode, adjustable signal swing, and automatic dual slew rate selection depending on HD/SD operational requirements. The GS1531 also includes a range of data processing functions including automatic standards detection and EDH support. The device can also insert TRS signals, calculate and insert line numbers and CRC’s, re-map illegal code words and insert SMPTE 352M payload identifier packets. All processing features are optional and may be enabled/disabled via external control pin(s) and/or host interface programming. *For new designs use GO1555 • • • Internal flywheel for noise immune TRS generation 20-bit / 10-bit CMOS parallel input data bus 148.5MHz / 74.25MHz / 27MHz / 13.5MHz parallel digital input Automatic standards detection and indication 1.8V core power supply and 3.3V charge pump power supply 3.3V digital I/O supply JTAG test interface Available in a Pb-free package small footprint (11mm x 11mm) Applications • • • SMPTE 292M Serial Digital Interfaces SMPTE 259M-C Serial Digital Interfaces DVB-ASI Serial Digital Interfaces 30573 - 7 February 2008 1 of 50 www.gennum.com GS1531 Data Sheet Functional Block Diagram IOPROC_EN/DIS SMPTE_BYPASS DETECT_TRS VCO_GND dvb-asi bypass sd/hd DIN[19:0] I/O Buffer & demux 20bit/10bit JTAG/HOST VCO_VCC LB_CONT DVB_ASI LOCKED CP_CAP BLANK HOST Interface / JTAG test SD/HD CS_TMS SCLK_TCK PCLK VCO VCO LF TRS insertion, Line number insertion, CRC insertion, data blank, codere-map and flywheel H Reset V RESET_TRST F Phase detector, charge pump, VCO control & power supply ClockCleaner™ SDO_EN/DIS DVB-ASI sync word insert & 8b/10b encode SMPTE 352M generation EDH generation & SMPTE scramble SDO P -> S SDO RSET SDIN_TDI GS1531 Functional Block Diagram 30573 - 7 SDOUT_TDO February 2008 2 of 50 GS1531 Data Sheet Contents Key Features .................................................................................................................1 Applications...................................................................................................................1 Description ....................................................................................................................1 Functional Block Diagram .............................................................................................2 1.

Detailed Description 4.1 Functional Overview The GS1531 is a multi-rate serializer with an integrated cable driver. When used in conjunction with the external GO1555/GO1525* Voltage Controlled Oscillator, a transmit solution at 1.485Gb/s, 1.485/1.001Gb/s or 270Mb/s is realized. The device has three different modes of operation which must be set through external device pins. When SMPTE mode is enabled, the device will accept 10-bit multiplexed or 20-bit demultiplexed SMPTE compliant data at both HD and SD signal rates. The device’s additional processing features are also enabled in this mode. In DVB-ASI mode, the GS1531 will accept an 8-bit parallel DVB-ASI compliant transport stream on its upper input bus. The serial output data stream will be 8b/10b encoded and stuffed. The GS1531’s third mode allows for the serializing of data not conforming to SMPTE or DVB-ASI streams. The provided serial digital outputs feature a high impedance mode, output mute on loss of parallel clock and adjustable signal swing. The output slew rate is automatically controlled by the SD/HD setting. In the digital signal processing core, several data processing functions are implemented including SMPTE 352M and EDH data packet generation and insertion, and automatic video standards detection. These features are all enabled by default, but may be individually disabled via internal registers accessible through the GSPI host interface. Finally, the GS1531 contains a JTAG interface for boundary scan test implementations. *For new designs use GO1555 4.2 Parallel Data Inputs Data inputs enter the device on the rising edge of PCLK as shown in Figure 4-1. The input data format is defined by the setting of the external SD/HD, SMPTE_BYPASS and DVB_ASI pins and may be presented in 10-bit or 20-bit format. The input data bus width is controlled independently from the internal data bus width by the 20bit/10bit input pin. 30573 - 7 February 2008 22 of 50 GS1531 Data Sheet PCLK DIN[19:0] DATA Control signal input tSU tIH Figure 4-1: PCLK to Data Timing 4.2.1 Parallel Input in SMPTE Mode When the device is operating in SMPTE mode, see SMPTE Mode on page 25, both SD and HD data may be presented to the input bus in either multiplexed or demultiplexed form depending on the setting of the 20bit/10bit input pin. In 20-bit mode, (20bit/10bit = HIGH), the input data format should be word aligned, demultiplexed luma and chroma data. Luma words should be presented to DIN[19:10] while chroma words should occupy DIN[9:0]. In 10-bit mode, (20bit/10bit = LOW), the input data format should be word aligned, multiplexed luma and chroma data. The data should be presented to DIN[19:10]. DIN[9:0] will be high impedance in this mode. 4.2.2 Parallel Input in DVB-ASI Mode When operating in DVB-ASI mode, see DVB-ASI mode on page 26, the GS1531 requires the input data bus to be configured for 10-bit operation (20bit/10bit = LOW). The device accepts 8-bit data words on DIN[17:10] such that DIN17 = HIN is the most significant bit of the encoded transport stream data and DIN10 = AIN is the least significant bit. In addition, DIN19 and DIN18 are configured as the DVB-ASI control signals INSSYNCIN and KIN respectively. See DVB-ASI mode on page 26 for a description of these DVB-ASI specific input signals. The pins DIN[9:0] are high impedance when the GS1531 is operating in DVB-ASI mode. 4.2.3 Parallel Input in Data-Through Mode When operating in Data-Through mode, see Data-Through Mode on page 28, the GS1531 passes data presented to the parallel input bus to the serial output without performing any encoding or scrambling. The input data bus width accepted by the device in this mode is controlled by the setting of the 20bit/10bit pin. 30573 - 7 February 2008 23 of 50 GS1531 Data Sheet 4.2.4 Parallel Input Clock (PCLK) The frequency of the PCLK input signal required by the GS1531 is determined by the input data format. Table 4-1 below lists the possible input signal formats and their corresponding parallel clock rates. NOTE: DVB-ASI input requires a 10-bit wide input data bus (20bit/10bit = LOW).

In this mode, the parallel data will be scrambled according to SMPTE 259M or 292M, and NRZ-to-NRZI encoded prior to serialization. 4.3.1 Internal Flywheel The GS1531 has an internal flywheel which is used in the generation of internal / external timing signals, and in automatic video standards detection. It is operational in SMPTE mode only. The flywheel consists of a number of counters and comparators operating at video pixel and video line rates. These counters maintain information about the total line length, active line length, total number of lines per field / frame and total active lines per field / frame for the received video standard. When DETECT_TRS is LOW, the flywheel will be locked to the externally supplied H, V, and F timing signals. When DETECT_TRS is HIGH, the flywheel will be locked to the embedded TRS signals in the parallel input data. Both 8-bit and 10-bit TRS code words will be identified by the device. The flywheel 'learns' the video standard by timing the horizontal and vertical reference information supplied a the H, V, and F input pins, or contained in the TRS ID words of the received video data. Full synchronization of the flywheel to the received video standard therefore requires one complete video frame. Once synchronization has been achieved, the flywheel will continue to monitor the received TRS timing or the supplied H, V, and F timing information to maintain synchronization. 4.3.2 HVF Timing Signal Extraction As discussed above, the GS1531's internal flywheel may be locked to externally provided H, V, and F signals when DETECT_TRS is set LOW. The H signal timing should also be configured via the H_CONFIG bit of the internal IOPROC_DISABLE register as either active line based blanking or TRS based blanking, see Packet Generation and Insertion on page 30. Active line based blanking is enabled when the H_CONFIG bit is set LOW. In this mode, the H input should be HIGH for the entire horizontal blanking period, including the EAV and SAV TRS words. This is the default H timing assumed by the device. When H_CONFIG is set HIGH, TRS based blanking is enabled. In this case, the H input should be set HIGH for the entire horizontal blanking period as indicated by the H bit in the associated TRS words. The timing of these signals is shown in Figure 4-2. 30573 - 7 February 2008 25 of 50 GS1531 Data Sheet PCLK LUMA DATA OUT 3FF 000 000 XYZ (eav) XYZ (eav) 3FF 000 000 XYZ (sav) XYZ (sav) CHROMA DATA OUT 3FF 000 000 3FF 000 000 H V F H:V:F TIMING - HD 20-BIT INPUT MODE PCLK MULTIPLEXED Y/Cr/Cb DATA OUT H V F 3FF 3FF 000 000 000 000 XYZ (eav) XYZ (eav) H:V:F TIMING AT EAV - HD 10-BIT INPUT MODE PCLK MULTIPLEXED Y/Cr/Cb DATA OUT H V F 3FF 3FF 000 000 000 000 XYZ (sav) XYZ (sav) H;V:F TIMING AT SAV - HD 10-BIT INPUT MODE PCLK CHROMA DATA OUT 3FF 000 3FF 000 LUMA DATA OUT H V F H_CONFIG = HIGH 000 XYZ (eav) 000 XYZ (SAV) H SIGNAL TIMING: H_CONFIG = LOW H:V:F TIMING - SD 20-BIT INPUT MODE PCLK MULTIPLEXED Y/Cr/Cb DATA OUT H V F 3FF 000 000 XYZ (eav) 3FF 000 000 XYZ (sav) H:V:F TIMING - SD 10-BIT INPUT MODE Figure 4-2: H, V, F Timing 4.4 DVB-ASI mode To operate the GS1531 in DVB-ASI mode, set the SMPTE_BYPASS and 20bit/10bit pins LOW, and the DVB_ASI and SD/HD pins HIGH. 30573 - 7 February 2008 26 of 50 GS1531 Data Sheet 4.4.1 Control Signal Inputs In DVB-ASI mode, the DIN19 and DIN18 pins will be configured as DVB-ASI control signals INSSYNCIN and KIN respectively. When INSSYNCIN is set HIGH, the device will insert K28.5 sync characters into the data stream. This function is used to assist system implementations where the GS1531 may be preceded by an external data FIFO. Parallel DVB-ASI data may be clocked into the FIFO at some rate less than 27MHz. The INSSYNCIN input may then be connected to the FIFO empty signal, thus providing a means of padding up the data transmission rate to 27MHz. See Figure 4-3. NOTE: 8b/10b encoding will take place after K28.5 sync character insertion. KIN should be set HIGH whenever the parallel data input is to be interpreted as any special character defined by the DVB-ASI standard (including the K28.5 sync character). This pin should be set LOW when the input is to be interpreted as data. NOTE: When operating in DVB-ASI mode, DIN[9:0] become high impedance.
