... Ordering number : EN*5240 Preliminary Overview The LC895124 is the next-generation version of the LC89512 and is a CD-ROM decoder that includes a SCSI interface that supports the high-speed transfers (10 MB/s) of the FAST SCSI standard. Functions CD-ROM ECC function, subcode read function, SCSI interface Features • On-chip SCSI interface (with built-in SCAM selection register) • ...

... Applications that use DRAM must insert resistors in the CAS and RAS lines, connect capacitors between these lines and ground, and take any other measures necessary to prevent undershoot in the DRAM related circuits. 5. Since these circuits include buffers that sink 48 mA, adequate noise prevention measures must be applied. LC895124 Type: I: Input pin, O: Output pin, B: Bidirectional pin, P: Power supply pin, NC: No connection pin Function ...

... The main clock for the ECC and SCSI blocks. These pins are enabled for oscillator operation by setting X1EN (pin 89). The LC895124 is designed so that the ECC and SCSI blocks can also be operated asynchronously. This means that precise 10-MB/s synchronous transfers can be achieved by providing a 20-MHz input to XTALCK1 and XTAL1 ...
