GC5316SEK FEATURES
GC5316SEK Description
The GC5316 is a high-density multi-channel communications signal processor integrated circuit that provides bothdigital downconversion and digital upconversion optimized for cellular base transceiver systems. The devicesupports both UMTS and CDMA2000 (CDMA) air interface cellular standards.The chip provides up to 24 CDMA digital downconverter (DDC) and digital upconverter (DUC) channels or 12 UMTSDDC and DUC channels. The GC5316 can also support a combination of CDMA and UMTS channels. The DDC andDUC channels are independent and operate simultaneously.The chip is ideal for cellular base transceiver systems where a large number of digital radio channels are required.Each of the 24 CDMA (or 12 UMTS) channels can operate independently. On the DDC side there are four 16 bit inputports that can accept real or complex input data. The input ports are driven with parallel data, typically from ananalog-to-digital converter. Each downconverter channel can be programmed to accept data from any one of the fourinput ports.On the DUC side, there are four 18-bit output ports. Each output port can sum any of the DUC channels in adaisy-chain fashion. This permits creating a stack of CDMA or UMTS signals. These ports can output either real orcomplex data. Real output data would generally drive one or more D/A converters and output the stack of signalsat an intermediate frequency (IF). Complex data (at baseband or an IF) is used when a quadrature modulatorupconversion scheme is employed. Complex output data can also be used when the output stack is further processedusing crest factor reduction or power amplifier predistortion techniques.Table of Contents1Description. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12GC5316 Receive. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 33GC5316 Transmit. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 254GC5316 General Control45. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .5GC5316 Programming. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 486GC5316 Pin Description. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 627Specification70. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .���������� ���� ����������� �� ������� �� �� ����������� ����� ��������������� �� �������������� ��� ��� ����� �� ����� ����������� �������� ������������������� ���������� ���� ��� ����������� ������� ������� �� ��� �����������Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instrumentssemiconductor products and disclaimers thereto appears at the end of this data sheet.www.ti.comCopyright 2004, Texas Instruments Incorporated
