S6006

The S6006 is designed as one kind of evaluation manual which describes two evaluation boards,it allows demonstration of AMCC's S3015/S3016 E4/STM-1/OC-3 SONET/SDH/ATM interface circuits. This document provides information on board contents and layout. It should be used in conjunction with the S3015/S3016 data sheet, which contains full technical details on chip operation.

An onboard DIP switch provides additional control capability on the transmitter board. The following five signals are controlled by means of the DIP switch: SERDATEN. TTL input. Enables the loopback path from the S3015 to the S3016. The data from the SERDATIP/N inputs will be CMI-encoded and sent to the S3016, where it will be decoded and output on the SERDATOP/N pins.XFRMEN. TTL input. Enables the transformer outputs TX_OUT and MON_OUT.CMISEL. TTL input. Selects CMI or NRZ. Logic High selects CMI mode, and Logic Low selects NRZ mode.

And the jumper configuration labeled JP1 on both boards allow the user to control whether an onboard crystal reference or external clock reference is used (see Crystal Reference above). Jumper A is installed when an external reference is used, and Jumper B is installed when the onboard crystal reference is used.
