M21324 SD, HD, 2xHD Cable Equalizer The M21324 is a high-speed, low-power, adaptive co-axial cable equalizers designed to increase the maximum low-jitter transmission distance of serial digital interface SDI video signals and DVB-ASI across commonly used bandwidth-limiting 75Ω coaxial cable. This device automatically optimizes the transfer function based on the bit rate and cable length to minimize the inter-symbol interference ISI jitter caused by the cable and to remove the DC offset components introduced with the pathological test pattern and AC coupling in systems. The M21324 is designed to support 2xHD data rates from 143 Mbps to 2970 Mbps. The low-noise, high-gain equalizer allows for low jitter 2xHD transmissions up to 100m Belden 1694A and HD transmissions up to a length of 200m Belden 1694A and 120m Belden For SD data rates, cable lengths up to 400m Belden 1694A and 300m Belden 8281 are supported. The M21324 shares the same footprint as the GS2974A, GS1574/GS1574A or GS9074A, except that the M21324 has a shared Signal Detect/Mute function pin, while the GS2974A, GS1574/1574A and GS9074A have separate CD and mute pins. • SMPTE Coaxial Cable Interface • Studio video applications • Broadcast video applications • Distribution video applications Standards Compliance • SMPTE 259M, SMPTE 292M, SMPTE 344M, SMPTE 424M complaint • Supports DVB-ASI 270 Mbps • Adaptive cable equalization • Optimized data rate from 143 Mbps to Gbps • Typical equalized length of Belden 1694A cable 100m at Gbps, 200m at Gbps, and 400m at 270 Mbps • Programmable mute level • Manual bypass mode • Differential CML outputs 50 Ω on-chip terminations • Single 3.3V power supply • Small form factor 4x4mm, 16-pin MLF package • Pb-free and RoHS compliant • Extended operating temperature range to +85 °C Functional Block Diagram M21324 Cable Equalizer SD/ MUTE THRESH CONTROL LOGIC INPUT BUFFER EQUALIZER CORE DC RESTORE OUTPUT BUFFER 21324-DSH-001-C EQ_ BYP Mindspeed Mindspeed Proprietary and Confidential November 2009 Ordering Information Package Operating Data Rate Operating Temperature M21324G-13* 16-pin MLF RoHS compliant Mbps °C to 85 °C * Consult the price list for exact part number when ordering. * The letter ‘G’ designator after the part number indicates a RoHS-compliant package.

M21324 SD, HD, 2xHD Cable Equalizer

The M21324 is a high-speed, low-power, adaptive co-axial cable equalizers designed to increase the maximum low-jitter transmission distance of serial digital interface SDI video signals and DVB-ASI across commonly used bandwidth-limiting 75Ω coaxial cable. This device automatically optimizes the transfer function based on the bit rate and cable length to minimize the inter-symbol interference ISI jitter caused by the cable and to remove the DC offset components introduced with the pathological test pattern and AC coupling in systems.

The M21324 is designed to support 2xHD data rates from 143 Mbps to 2970 Mbps.

The low-noise, high-gain equalizer allows for low jitter 2xHD transmissions up to 100m Belden 1694A and HD transmissions up to a length of 200m Belden 1694A and 120m Belden For SD data rates, cable lengths up to 400m Belden 1694A and 300m Belden 8281 are supported.

The M21324 shares the same footprint as the GS2974A, GS1574/GS1574A or GS9074A, except that the M21324 has a shared Signal Detect/Mute function pin, while the GS2974A, GS1574/1574A and GS9074A have separate CD and mute pins.
