  • Page 7: Introduction

    Introduction The Texas Instruments (TI) TLK1501 serdes evaluation module (EVM) board is used to evaluate the TLK1501 device(VQFP) and associated optical inter- face (NetLight ) for point-to-point data transmission applications. The board enables the designer to connect 50 Ω parallel buses to both transmitter and receiver connectors.

  • Page 8: Introduction

    The board can be used to evaluate device parameters while acting as a guide for high-speed board layout. The evaluation board can be used as daughter boards that are plugged into new or existing designs. Since the TLK1501 operates over a wide range of frequencies, the designers will need to optimize their design for the frequency of interest.

    L3 that is installed in the default configuration. Thus, only the VDD connection is necessary to energize the TLK1501 device in the default configuration. In all sections of the board, the ground planes are common and each ground plane is tied together at every component ground connection.

  • Page 10: Default Transceiver Board Configuration As Shipped

    The board is normally delivered in a default configuration that requires external clock and data inputs. The TLK1501 is shipped with jumpers for default operation. Table 2–1 shows the default configuration for sending data. Table 2–1. Default Transceiver Board Configuration as Shipped...

    Figure 2–1. The serial loopback allows the designer to evaluate most of the functions of both transmitter and receiver sections of the TLK1501 device. To test a system, a parallel bit error rate tester (BERT) generates a predefined parallel bit pattern. The pattern is connected to the transmitter through parallel connectors TD0–TD15.

    Direct connection is achieved only if the optical interface supports the current mode logic levels of the TLK1501 device (VDD – 1 V). If the optics module does not support or can not be biased to the CML levels then ac-coupling must be used.
