GS1524A Adaptive Cable Equalizer Features • • • • • • • • • • • • • • SMPTE 292M, SMPTE 344M and SMPTE 259M compliant Automatic cable equalization Multi-standard operation from 143Mb/s to 1.485Gb/s Supports DVB-ASI at 270Mb/s Pb-free and RoHS Compliant Pin compatible with the GS9064 Cable Equalizer Manual bypass (useful for low data rates with slow rise/fall times) Performance optimized for 270Mb/s and 1.485Gb/s Typical equalized length of Belden 1694A cable: 200m at 1.485Gb/s, 350m at 270Mb/s 50Ω differential output (with internal 50Ω pull-ups) Manual output mute or programmable mute based on max cable length adjust Cable length indicator for SMPTE 259M inputs Single 3.3V power supply operation Operating temperature range: 0°C to +70°C Description The GS1524A is a second-generation high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75Ω co-axial cable. The GS1524A is designed to support SMPTE 292M, SMPTE 344M and SMPTE 259M, and is optimized for performance at 270Mb/s and 1.485Gb/s. The GS1524A features DC restoration to compensate for the DC content of SMPTE pathological test patterns. The device also incorporates a Cable Length Indicator (CLI) that provides an indication of the amount of cable being equalized for data rates up to 360Mb/s. A voltage programmable mute threshold (MCLADJ) is included to allow muting of the GS1524A output when an approximate selected cable length is reached for SMPTE 259M signals. This feature allows the GS1524A to distinguish between low amplitude SD-SDI signals and noise at the input of the device. The bidirectional CD/MUTE pin indicates the presence of a valid signal at the input of the GS1524A in addition to functioning as a mute control input. The outputs of the GS1524A will be forced to a mute state when an invalid input reference signal is applied to the input of the device or the application layer sets the CD/MUTE pin HIGH. If the application layer forces CD/MUTE LOW, the serial digital output of the device will always be active. Power consumption is typically 265mW using a 3.3V power supply. The GS1524A is Pb-free, and the encapsulation compound does not contain halogenated flame retardant (RoHS Compliant).

Detailed Description The GS1524A is a high speed BiCMOS IC designed to equalize serial digital signals. The GS1524A can equalize both HD and SD serial digital signals, and will typically equalize 200m of Belden 1694A cable at 1.485Gb/s and 350m at 270Mb/s. The GS1524A/ is powered from a single +3.3V power supply and consumes approximately 265mW of power. GS1524A Adaptive Cable Equalizer Data Sheet 28852 - 5 June 2009 10 of 16 4.1 Serial Digital Inputs The serial data signal may be connected to the input pins (SDI/SDI) in either a differential or single ended configuration. AC coupling of the inputs is recommended, as the SDI and SDI inputs are internally biased at approximately 1.8V. 4.2 Cable Equalization The input signal passes through a variable gain equalizing stage whose frequency response closely matches the inverse of the cable loss characteristic. In addition, the variation of the frequency response with control voltage imitates the variation of the inverse cable loss characteristic with cable length. The edge energy of the equalized signal is monitored by a detector circuit which produces an error signal corresponding to the difference between the desired edge energy and the actual edge energy. This error signal is integrated by both an internal and an external AGC filter capacitor providing a steady control voltage for the gain stage. As the frequency response of the gain stage is automatically varied by the application of negative feedback, the edge energy of the equalized signal is kept at a constant level which is representative of the original edge energy at the transmitter. The equalized signal is also DC restored, effectively restoring the logic threshold of the equalized signal to its correct level independent of shifts due to AC coupling. The digital output signals have a nominal voltage of 750mVpp differential, or 375mVpp single ended when terminated with 50Ω as shown in Figure 4-1. +187.5mV VCM = 2.925V typical SDO -187.5mV SDO 50 50 +187.5mV VCM = 2.925V typical -187.5mV Figure 4-1: Typical Output Voltage Levels 4.3 Programmable Mute Output and Cable Length Indicator For SMPTE 259M inputs, the GS1524A incorporates a programmable threshold output mute (MCLADJ) and an analog cable length indicator (CLI). GS1524A Adaptive Cable Equalizer Data Sheet 28852 - 5 June 2009 11 of 16 MCLADJ In applications where there are multiple input channels using the GS1524A, it is advantageous to have a programmable mute output to avoid signal crosstalk. The output of the GS1524A can be muted when the input signal decreases below a certain input level. This threshold is determined using the input voltage applied to the MCLADJ pin. The MCLADJ pin may be left unconnected for applications where output muting is not required. This feature has been designed for use in applications such as routers where signal crosstalk and circuit noise cause the equalizer to output erroneous data when no input signal is present. The use of a Carrier Detect function with a fixed internal reference does not solve this problem since the signal to noise ratio on the circuit board could be significantly less than the default signal detection level set by the on chip reference. NOTE: MCLADJ is only recommended for data rates up to 360Mb/s. CLI The output voltage of the CLI pin is an approximation of the amount of cable present at the GS1524A input. With 0m of cable, 800mV input signal levels, and a data rate of 270Mb/s, the CLI output voltage is approximately 2.5V. As the cable length increases, the CLI voltage decreases providing an approximate correlation between the CLI voltage and cable length. NOTE: CLI is only recommended for data rates up to 360Mb/s. 4.4 Mute and Carrier Detect In addition to the programmable mute output and cable length indicator, the GS1524A includes a multi-function CD/MUTE bidirectional pin that provides the following functions: INPUT (MUTE) Applying a HIGH INPUT to the CD/MUTE pin forces the GS1524A outputs to a muted condition. The minimum voltage required to force the outputs to a muted condition is listed in the DC electrical characteristics table. In this condition the outputs will be latched to the last logic level present at the output to avoid signal crosstalk. Applying a LOW INPUT to the CD/MUTE pin will force the GS1524A outputs to remain active regardless of the length of input cable and the voltage applied to the MCLADJ pin. See the DC electrical characteristics table for voltage levels. OUTPUT (CD) When used as an OUTPUT, the CD/MUTE pin will indicate the presence of a valid input signal. When CD/MUTE is LOW, a valid input signal has been detected at the input of the device. When CD/MUTE is HIGH, the input signal is invalid. This pin will indicate loss of carrier for data rates greater than 19Mb/s. NOTE: The CD/MUTE pin is not functional in BYPASS mode.

Application Information 5.1 PCB Layout Special attention must be paid to component layout when designing serial digital interfaces for HDTV. An FR-4 dielectric can be used, however, controlled impedance transmission lines are required for PCB traces longer than approximately 1cm. Note the following PCB artwork features used to optimize performance: • • • • PCB trace width for HD rate signals is closely matched to SMT component width to minimize reflections due to change in trace impedance. The PCB ground plane is removed under the GS1524A input components to minimize parasitic capacitance. The PCB ground plane is removed under the GS1524A output components to minimize parasitic capacitance. High speed traces are curved to minimize impedance changes. 5.2 Typical Application Circuits CLI CD/MUTE VCC VCC 10n 10n BNC GS1524A 6.4n 1u 75 1u 1 2 3 4 5 6 7 8 + 1u CLI VCC VEE SDI SDI VEE AGC+ AGCCD/MUTE VCC VEE SDO SDO VEE MCLADJ BYPASS 16 15 14 13 12 11 10 9 + 4u7 SDO + SDO 4u7 75 37.4 MCLADJ BYPASS NOTE: All resistors in Ohms, capacitors in Farads, and inductors in Henrys, unless otherwise noted.
