DESCRIPTION

· The M21355 is a quad serial digital video reclocker supporting SDI data rates from 270Mbps to 2970Mbps, compliant with SMPTE 424M, SMPTE 292M, SMPTE 259M, and DVB-ASI standards.

· It features integrated trace equalization, automatic rate detect (ARD) circuitry, and a 16:4 crosspoint switch at the input.

· The device operates with a single 27MHz external crystal and provides retimed serial outputs with low jitter.

· It supports multi-voltage operation (1.2V, 1.8V, 2.5V, 3.3V) and consumes only 135mW per channel at 1.2V in 3G-SDI mode.

· The M21355 is available in a 10mm x 10mm, 72-pin QFN package.

FEATURES

· Independent quad-channel multi-rate reclocker for high-density designs.

· 0.6UI input jitter tolerance for robust error-free performance.

· Integrated 50Ω input termination and 40” FR4 trace equalization.

· Output de-emphasis and electrically isolated supply rails for DC coupling flexibility.

· Configurable via I2C, SPI, or external I2C EEPROM, with hardware configuration options.

· Loss of lock (LOL), loss of signal (LOS), and data rate indication for diagnostics.

· Industrial temperature range (-40°C to +85°C) for enhanced design tolerance.

APPLICATIONS

· High-density video processing systems requiring multi-rate SDI reclocking.

· Broadcast and professional video equipment compliant with SMPTE and DVB-ASI standards.

· Low-power designs with minimal heat dissipation requirements.

· Systems needing flexible DC-coupled interfaces with multi-voltage support.

· Industrial-grade applications requiring robust performance in extreme temperatures.
