E1XC EVALUATION DAUGHTERBOARD
1 OVERVIEW
The PM6541 E1XC EVBD evaluation daughterboard allows for the test, evaluation
and demonstration of the PMC PM6341 E1XC device. It is also compatible with the
PM4341 T1XC device. This daughterboard can be used standalone with up to two
E1XC devices but has been especially designed to mate with the PMC PM1501
EVMB evaluation motherboard to form a complete evaluation system. All required
decoding logic is provided on the E1XC EVBD daughterboard to give the EVMB
direct access to all registers of both E1XC devices.
All of the principal connections to both devices have been brought out to header
strips for convenient test access. E-1 digital interfaces are provided on a header
strip and BNC or mini-bantam connectors are provided for E-1 analog signals. Both
75 Ω and 120 Ω interfaces are provided. The backplane interfaces of each device
are accessible through header strips and the devices can be interconnected back to
back, effectively creating a jitter-attenuating format converter by dropping in shorting
connectors into specific DIP sockets.
Clocks for the backplane are provided by a T1/CEPT digital trunk DPLL which
provides a synchronized 1.544 MHz, 2.048 MHz, or 4.096 MHz signal. The PLL can
be easily bypassed to allow direct drive of the backplane with an appropriate
oscillator. A prototype area has been provided for breadboarding more complex
applications.
The E1XC EVBD evaluation daughterboard is configured, monitored, and powered
through an edge connector that is designed to mate with the EVMB evaluation
motherboard
