Semtech Corporation GS1674
The GS1674 is a high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75Ω coaxial cable. The device is optimized for performance at 270Mb/s and 1.485Gb/s, and features DC restoration to compensate for the DC content of SMPTE pathological test patterns. The Carrier Detect output pin (CD) indicates whether a valid input signal has been detected.| Part No. | GS1674 |
