1 / 9 page PRELIMINARY GENLINX ™ II EB-RD35 Evaluation Board EB-RD35 BLOCK DIAGRAM Document No. VB2930 - 1 INTRODUCTION The EB-RD35 is an evaluation and reference design platform for Routing and Distribution applications using the GENLINX™ II GS9024 Equalizer, the GS9035 Reclocker, and the GS9028 Cable Driver. CIRCUIT DESCRIPTION A functional block diagram is shown below and illustrates the primary circuit functions. These include equalization, reclocking, and driving 75 Ω co-axial cables. A complete schematic is also included. The EB-RD35 accepts a serial digital data input signal which first goes into the GS9024 equalizer. Equalization of the input signal is completely automatic for signal attenuation due to cable length from 0dB to in excess of 30dB. The signal strength/carrier detect output of the equalizer, which is proportional to the amount of equalization taking place, is available via test point TP3. Also available as an output, is the equalizer "Output Eye Monitor" signal via a SMA connector (J6). The signal strength/carrier detect and Output Eye Monitor are useful diagnostic outputs. After equalization, the differential data signal is passed to the GS9035 reclocker which generates clock and retimed data signals. In addition, the complementary serial clock output signals are available at BNC connectors J2 and J3. The GS9035 also drives data rate indication LEDs and a LOCK LED which is provided to visually indicate when the reclocker has locked to the incoming video signal. The reclocked data signals are then supplied to the GS9028 cable driver which provides two complementary data outputs at BNC connectors J4 and J5. The GS9028 is configured to drive 75 Ω co-axial cables with SMPTE defined 800mV levels. BOARD SET-UP AND TEST The board is configured in SMPTE, auto-tune mode and supports five data rates: 143Mb/s, 177Mb/s, 270Mb/s, 360Mb/s, and 540Mb/s. LED indicators are used to indicate when the device is LOCKed and the detected data rate as shown below: SS2 SS1 SS0 143Mb/s 0 0 0 177Mb/s 0 0 1 270Mb/s 0 1 0 360Mb/s 0 1 1 540Mb/s 1 0 0 The GS9035 can also be configured for manual mode by first putting the AUTO/MANUAL jumper (JMP2) into the 2- 3 position. Then jumpers JMP[7:5] are set accordingly. Note that whenever the AUTO/MANUAL input of the GS9035 is HIGH (auto mode), jumpers JMP[7:5] should be left floating to avoid bus contention.
