CROSS-REFERENCE ALTERNATIVE

COS6143SR is a Chinese-manufactured Video Driver / Buffer from COSINE (科山芯创) that cross-references to FMS6143CSX (ONSEMI), and also to SGM9119YS8G/TR, THS7314.

It is a SOP8 device positioned as a domestic-supply option against the imported: shorter lead times, no allocation risk and a stable price for volume production. Because the parts are not pin-identical in every case, the engineering checklist below lists what to verify before you commit.

COS6143SR — Video Driver / Buffer, alternative to FMS6143CSX

COS6143SR is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for FMS6143CSX (ONSEMI), SGM9119YS8G/TR (圣邦微), THS7314 (TI). Imported parts in this class are frequently subject to allocation, long lead times and steep price swings. A Chinese-manufactured equivalent removes that exposure: the parts are production-validated in industrial, consumer and automotive designs and ship from stock on a short lead time.

Cross-reference chart — which imported parts does COS6143SR replace?

Every imported part number that COS6143SR is published as a cross-reference alternative to, per the COSINE (科山芯创) 2025 selection table:

What to verify before substituting COS6143SR

These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:

  1. Number of channels and gain (typically 6 dB / ×2) — and whether the had an internal gain network
  2. Input DC restore/clamp and bias circuitry, which is often integrated in the
  3. Output drive into a 150 Ω (or double-terminated 75 Ω) video load
  4. Bandwidth and differential gain/phase, which determine picture quality
  5. Supply range and single-supply operation
  6. Package and pinout, including the bias and clamp pins

Typical applications

  • Set-top boxes and video decoders
  • Security camera and DVR outputs
  • Automotive infotainment and reversing cameras
  • Portable media players
  • Video distribution and buffering
  • Industrial vision systems
