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:

Cross-reference means functional equivalence in the same application role. It is not a blanket claim of pin-for-pin identity — confirm package, pinout and the parameters listed below before you release a design change.

Device information

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
