78P2352

The 78P2352 is designed as one kind of Teridian's second generation Line Interface Unit (LIU) device that can be used in wide range of applications such as (1)central office interconnects; (2)DSLAMs; (3)add drop multiplexers (ADMs); (4)multi service switches; (5)digital microwave radios. Also this device can interface to 75 coaxial cable using CMI coding or directly to a fiber optics transceiver module using NRZ coding.

Features of the 78P2352 are:(1)ITU-T G.703 compliant cable driver for 139.264 Mbps or 155.52 Mbps CMI-coded coax transmission; (2)Integrated adaptive CMI equalizer and CDR in receive path handles over 12.7dB of cable loss; (3)Serial, LVPECL system interface with integrated CRU in transmit path for flexible NRZ to CMI conversion.; (4)4-bit parallel CMOS system interface with master and slave Tx clock modes.; (5)Selectable LVPECL compatible NRZ media interface for 155.52 Mbps optical transmission.; (6)Configurable via HW control pins or 4-wire serial port interface; (7)Compliant with ANSI T1.105.03-1994; ITU-T G.751, G.813, G.823, G.825, G.958; and Telcordia GR-253-CORE for jitter performance.; (8)Receiver Loss of Signal (LOS) detection compatible with ITU-T G.783; (9)Operates from a single 3.3V supply; (10)Standard and thermally enhanced 128-pin JEDEC LQFP package options.

The absolute maximum ratings of the 78P2352 can be summarized as:(1)Supply Voltage (Vdd): -0.5 to 4.0 VDC;(2)Storage Temperature: -65 to 150 °C;(3)Junction Temperature: -40 to 150 °C;(4)Pin Voltage (CMIxP,CMIxN): Vdd + 1.5 VDC;(5)Pin Voltage (all other pins): -0.3 to (Vdd+0.6) VDC;(6)Pin Current: ±100 mA.etc. If you want to know more information about the 78P2352, please download the datasheet in www.seekic.com or www.chinaicmart.com .
