62 / 75 page  GC5316 SLWS154A − JANUARY 2004 − REVISED MARCH 2004 www.ti.com 62 gainfora U 0100 0C 0 16 8192 This is the unsigned gain that is multiplied with the CDMA channel A or UMTS channel input signal. The gain multiply is calculated as gainfora/8192. gainforb U 0100 0D 0 16 8192 This is the unsigned gain that is multiplied with the CDMA channel B input signal. cic_auto_flush_dis E 0100 10 12 4 0 Disables the automatic flush feature in the CIC accumulators. cic_flush_test E 0100 10 8 4 0 Forces an overflow detection in the CIC only on a rising edge of this bit, therefore it must be programmed to ‘0’ and then back to ‘1’ for the edge to occur. cic_flush_clear E 0100 10 4 4 0 Clears an overflow error manually when set, again only on a rising edge does this occur. serp_tran_bits U 0100 1B 11 5 17 Number of input bits per sample−1; for 18 bits, this is set to {10001}. serp_tran_fsdel D 0100 1B 8 2 1 Delay between frame sync output and MSB of serial data {3, 2, 1, 0}. serp_tran_4pin D 0100 1B 7 1 0 Selects 2-pin mode when cleared and 4-pin mode when set. serp_tran_fsinvl U 0100 1B 0 7 50 Transmit serial interface frame sync interval in bit clocks. serp_tran_clkdiv U 0100 1C 0 4 1 Transmit serial interface clock divider rate−1; 0 is full rate, and 15 divides the clock by 16. For example, to run the serial interface at 1/4 the transmit clock, set serp_tran_clkdiv(3:0) = 0011. ssel_pilot U 0120 0B 4 3 0 Selects the sync source for the DUC pilot code generator. 6 GC5316 Pin Description 6.1 Transmit Section Signals SIGNAL NAME BALL DESIG TYPE DESCRIPTION txclk K26 input Transmit clock input txin_0_a T23 input DUC 0 serial in data.
