EV3037QF
SONET/SDH/ATM STS-12 TRANSCEIVER EVALUATION BOARD
July 2, 1999
EV3037QF
DESCRIPTION
The S3037 Evaluation Board provides a flexible platform for verifying the operation of the S3037 transceiver
interface circuit. This data sheet provides information on the board contents. It should be used in conjunction
with the S3037 data sheet, which contains full technical details on chip operation.
Figure 1 shows the outline of the S3037 Evaluation Board, and Figure 2 shows the block diagram of how the
S3037 Evaluation Board should be connected to test equipment for BER testing. In this configuration the S3037
is configured for use with the internal S3037 Clock Recovery Unit (CRU), using a 19.44 or 77.76 MHz reference
and operating at STS-12.

ELECTRICAL CONNECTIONS
Power Connections
Terminal posts are provided at the top edge of the board for V
CC
and V
EE
. The S3037 Evaluation Board can be
configured with PECL and Level Shifted (LSECL) I/O so the board can be configured to operate with different
types of standard test equipment. Figures 5 through 7 demonstrate the different types of input and output
waveforms that the S3037 Evaluation Board can output with the different voltage settings of V
CC
and V
EE
per
Table 1. Note the TTL I/O's voltage level will change to non-standard levels when the S3037 Evaluation Board is
powered by the different voltage.
