DESCRIPTION
The 78P2351R is Teridian’s second generation Line
Interface Unit (LIU) for 155 Mbit/s electrical SDH
interfaces (STM1e).
The device is a single chip
solution that includes an integrated Clock & Data
Recovery in both the transmit and receive paths for
easy, cost efficient NRZ to CMI conversion.
The device interfaces to 75
coaxial cable through
wideband transformers and can handle over 12.7dB
of cable loss.
By eliminating the needs for
synchronous clocks, the small 78P2351R (7x7mm
MLF package) is ideal for new STM1e (ES1) Small
Form-factor Pluggable (SFP) transceiver modules.
APPLICATIONS
STM1e SFP modules
SDH/ATM Line Cards
Add Drop Multiplexers (ADMs)
PDH/SDH Test Equipment
Digital Microwave Radios
Multi-Service Switches
FEATURES
ITU-T G.703 compliant, adjustable cable driver
for 155.52 Mbps CMI-coded coax transmission
Integrated adaptive CMI equalizer and CDR in
receive path handles over 12.7dB of cable loss
LVPECL-compatible
system
interface
with
integrated CDR in transmit path for flexible NRZ
to CMI conversion
Configurable via HW control pins or 4-wire serial
port interface
Compliant with ANSI T1.105.03-1994; ITU-T
G.813, G.825, G.958; and Telcordia GR-253-
CORE for jitter performance
Receive Loss of Signal (Rx LOS) detection
Receive Monitor Mode handles up to 20dB of
flat loss (at max 6dB cable loss)
Optional fixed backplane equalizer compensates
for up to 1.5m of trace
Operates from a single 3.3V supply
Available in a small 7x7mm 56-pin QFN
package
Industrial Temperature: -40C to +85C
