The LF2247 provides a coefficient register file containing four 32 x 11-bit registers which are capable of storing 32 different sets of filter coefficients for the multiplier array. All multiplier data inputs are user accessible and can be updated every clock cycle with either fractional or integer two’s complement data. The pipelined architecture has fully registered input and output ports and an asynchronous three-state output enable control to simplify the design of complex systems. The pipeline latency for all inputs is five clock cycles. A 25-bit accumulator path allows cumulative word growth which may be internally rounded to 16 bits. Output data is updated every clock cycle and may be held under user control. The data inputs/outputs and control inputs are registered on the rising edge of CLK. The Serial Data In signal, SDIN, is registered on the LF2247 BLOCK DIAGRAM D19-0 10 11 ENB1 D29-0 10 11 ENB2 22 D39-0 10 11 ENB3 D49-0 10 11 ENB4 22 MS LS S15-0 ACC FSEL OEN CLK TO ALL REGISTERS (EXCEPT COEFFICIENT REGISTERS) 25 OCEN Coefficient Register 1 (32 x 11-bit) Coefficient Register 2 (32 x 11-bit) Coefficient Register 3 (32 x 11-bit) Coefficient Register 4 (32 x 11-bit) A4-0 SEN SDIN SCLK SCLK 5 ENBA 16 COEFFICIENT REGISTER FILE SEN SCLK SEN SCLK SEN |
