... RAM. The extracted wobble frequency is supplied to the AT78C1507 companion chip which in turn synthesizes the write clock. The AT78C1507 is the companion chip to the AT78C1503 – DVD/CD Read Channel – and the AT78C1504 – DVD/CD Automatic Laser Power Controller. Working in conjunction with the read channel, the AT78C1507 is responsible for wobble clock synthesis for DVD-R and DVD-RAM formats ...
