  • by CL1 at pin 15. The direct path signal is clamped by the other CL1 switch to the dc level of the delayed path (including any offsets) to ensure there is no difference in clamping level between the two paths. During the period “SECAM 1”, the B.
  • Y signal is present and this is clamped to the delayed path dc level. Switch SECAM 1 is closed during this time and so the direct signal passes straight to the output. During the next line period (SECAM 2) there is no direct path signal; now switc.

It may be used as a baseband chroma correction circuit (with PAL), or as a chroma delay line (with SECAM). The device has been designed for use with the MC44000 as part of CHROMA 4, or with the MC44011, but may also be used as a general purpose delay line for other applications. • • • • • • • • Part of SYSTEM 4 Concept Works with Baseband Color Difference Signals PAL (4.43 MHz)/SECAM/NTSC Capability Uses 17.734475 MHz Clock with PAL/SECAM Signals 8–Bit Sampling at 1/6 Clock Frequency External Inputs (Satellite ....
