M21260
3G/HD/SD-SDI Quad Reclocker w/ External Rate Detection and 4x4 Input Crosspoint Switch
Overview
Description
The M21260 is a low power, high performance 4x4 video crosspoint with integrated quad video reclockers for 3G/HD/SD (42M-3.2G) professional video applications.
Features
- Fully independent, quad channel multi-rate video reclockers, SMPTE and DVB-ASI compliant:
- Hardwired control mode: 143, 177, 270, 360, 540, 1483.5/1485 Mbps, 2.975 Gbps
- Software control mode : 42 Mbps - 3.2 Gbps
- Bypass mode : 0 - 3.2 Gbps
- Integrated 4x4 crosspoint switch for data rates to 3.2 Gbps with a fully non-blocking architecture and broadcast / multicast functionality
- Integrated signal conditioning for improved signal integrity with inexpensive PCB materials or longer PCB trace lengths
- Very low power dissipation and flexible power supply support for reduced power supply and thermal management costs
- PCB layout friendly with 'pass through' I/O and high speed output polarity inversion
- Superior jitter generation (5mUI typical) and improved jitter tolerance in the high frequency band
- Integrated loop filter components and I/O termination resistors for simplified PCB designs and reduced cost
- Flexible I/O interfacing to CML, LVDS, and LVPECL with per channel output amplitude control
- Serial SPI 4 wire interface or hardwired interface control
- BIST features for PCB and system testing with fully independent transmitter and receiver:
- PRBS : 27 -1, 215 -1, 223 -1, 231 -1
- 8b/10 : CJTPAT, CRPAT, countdown
