EVALUATION BOARD
Introduction
The S2064 evaluation board provides a flexible platform for verifying the operation of the S2064 Quad Serial Back-
plane device. This document provides information on the evaluation board's contents. It should be used in
conjunction with the S2064 product data sheet. Contact your local AMCC field applications engineer or regional
sales manager to discuss any questions or concerns you may have.

Board Description
The top view of the EV2064 evaluation board is shown in Figure 1. The high speed differential LVPECL receive
RXxP/N, and transmit TXxP/N, where x = A through D, are brought in and out on SMA connectors as shown on the
left side of the board.

Revision 1.0 - November 18, 1999
The reference clock is brought in through the SMA connector labeled REFCLK. Power and ground are brought in
through the connector at the top of the board. The S2064 voltage is specified at 3.3V +/- 5%. Parallel I/O are
brought in and out on the connector banks on the right side and top of the board; there is one connector bank for
each channel (A through D). Input and output static control signals are controlled with the use of the DIP switch at
the bottom of the board. DIP switch settings are outlined in Table 1. Moving the switch to the on position creates a
logic 1 (High), moving it away from the on setting creates a logic 0 (Low).
Test Setups
The typical test performed with the S2064 evaluation board is jitter testing. In each case it is easiest to configure the
evaluation board for serial I/O, looping back the parallel I/O with jumpers. Serial I/O (parallel loopback) configuration
is shown in Figure 2 and described below.
DIP switch settings for parallel loopback:
RESET
HIGH
LPEN
LOW
RATE
HIGH or LOW (determined by desired serial data rate)
TMODE
HIGH
CLKSEL
HIGH or LOW (determined by desired reference clock rate)
CMODE
HIGH
CH-LOCK/TEST MODE
LOW
In order to configure the board for parallel loopback, the parallel input data must be clocked into the device with the TCLKx input
clocks as shown in Figure 2. This clock is provided by looping the RCxP output clock back into the respective TCLKx input with
one of the minicoax cables provided in the EV2064 Kit. These cables need only be connected for the channel(s) under test.
Table 1. DIP Switch Settings
DIP Name
Description
RESET
When Low, the S2064 is held in reset, When High, the S2064 operates normally.
LPEN
Loopback Enable. When Low, the device performs normal transceiver operation. When
High the serial output for each channel is looped back to its input. The serial outputs are
squelched when LPEN = High.
RATE
When Low the S2064 operates with the serial output rate equal to the VCO frequency.
When High the S2064 operates with the VCO internally divided by 2 for all functions.
TMODE
Transmit Mode Control. When TMODE is Low, REFCLK is used to clock data on
DINx[7:0], SOFx, and KGENx into the S2064. When TMODE is High, TCLKx is used to
clock data into the S2064. In Channel Lock mode (CH_LOCK HIGH), all four channels
are clocked by TCLKA. In independent mode (CH_LOCK LOW) each channel is clocked
by its respective TCLK.
CLKSEL
REFCLK Select input. This signal configures the PLL for the appropriate REFCLK fre-
quency. When CLKSEL = 0, the REFCLK frequency should equal the parallel word rate.
When CLKSEL = 1, the REFCLK frequency should be 1/2 the parallel word rate (and is
internally x2 multiplied).
CMODE
Clock Mode Control for receiver data stream. When Low, the rate of the parallel output
clock (RCxP/N) is 1/2 the data rate, for ping/pong clocking. When High, the rate of the
parallel output clock (RCxP/N) is equal to the data rate.
CH_LOCK/TESTMODE
Parallel input mode control. Channel Lock High locks all four channels together. (see
Device Specification). Channel Lock Low provides independent channel operation.
