The LF43891 is a video-speed digital filter that contains eight filter cells (taps) cascaded internally and a shift­and-add output stage. A 9 x 9 multi­plier, three decimation registers, and a 26-bit accumulator are contained in each filter cell. The output stage of the LF43891 contains a 26-bit accumulator which can add the contents of any filter stage to the output stage accu­mulator shifted right by 8 bits. 8-bit unsigned or 9-bit two’s complement format for data and coefficients can be independently selected.
Expanded coefficients and word sizes can be processed by cascading mul­tiple LF43891s to implement larger filter lengths without affecting the sample rate. By reducing the sample
9 x 9-bit Digital Filter
rate, a single LF43891 can process larger filter lengths by using multiple passes. The sampling rate can range from 0 to 40 MHz. Over 1000 taps may be processed without overflows due to the architecture of the device.
The output sample rate can be re­duced to one-half, one-third, or one­fourth the input sample rate by using the three decimation registers con­tained in every filter cell. Matrix multiplication, N x N spatial correla­tions/convolutions, and other 2-D operations for image processing can also be achieved using these registers.

FILTER CELL DESCRIPTION
9-bit coefficients are loaded into the C register (CIN8-0) and are output as COUT8-0 (the COENB signal enables the COUT8-0 outputs). The path taken by the coefficients varies according to the decimation mode chosen. With no decimation, the coefficients move directly from the C register, bypassing all decimation registers, and are available at the output on the following clock cycle. When decimation is chosen, the coefficient output is delayed by 1, 2, or 3 clock cycles depending on how many decimation registers the coefficients pass through (D1, D2, or D3). The number of decimation registers the coefficients pass through is determined by DCM1-0. Refer to Table 1 for choosing a decimation mode.
CIENB enables the C and D registers for coefficient loading. The registers are loaded on the rising edge of CLK when CIENB is LOW. CIENB is latched and delayed internally which enables the registers for loading one clock cycle after CIENB goes active (loading takes place on the second rising edge of CLK after CIENB goes LOW). Therefore, CIENB must be LOW one clock cycle before the coefficients are placed on the CIN8-0 inputs. The coefficients are held when CIENB is HIGH.

DIENB enables the X register for the loading of data. The X register is loaded on the rising edge of CLK when DIENB is LOW. DIENB is latched and delayed internally (load­ing takes place on the second rising edge of CLK after DIENB goes LOW). Therefore, DIENB must be LOW one clock cycle before the data is placed on the DIN8-0 inputs. The X register is loaded with all zeros when DIENB is HIGH.
The output of the C register (C8-0) and X register (X8-0) provide the inputs of the 9 x 9 multiplier. The multiplier is followed by two pipeline registers,
M REG0 and M REG1. The output of the multiplier is sign extended and is used as one of the inputs to the 26-bit adder. The output of the 26-bit accumulator provides the second input to the adder. Both the accumu­lator and T register are loaded simul­taneously with the output of the adder.
The accumulator is loaded with the output of the adder on every clock cycle unless cleared. Clearing the accumulator can be achieved using two methods. The first method, when both RESET and ERASE are LOW, causes all accumulators and all
3
registers in the device to be cleared together. RESET and ERASE are latched and delayed internally caus­ing the clearing to occur on the second clock cycle after RESET and ERASE go active.
The second method, when only ERASE is LOW, clears a single accu­mulator of a selected cell. The cell is selected using the ADR2-0 inputs (decoded to Cell n). ERASE is latched and delayed internally causing the clearing to occur on the second clock cycle after ERASE goes active. Refer to Table 2 for clearing registers and accumulators.

OUTPUT STAGE DESCRIPTION
The 26-bit adder contained in the output stage can add the contents of any filter cell accumulator (selected by ADR2-0) with the 18 most significant bits of the output buffer. The result is stored back into the output buffer. The complete operation takes only one clock cycle. The eight least significant bits of the output buffer are lost.
The Zero multiplexer is controlled by the SHADD input signal. This allows selection of either the 18 most signifi­cant bits of the output buffer or all zeros for the adder input. When SHADD is LOW, all zeros will be selected. When SHADD is HIGH, the 18 most significant bits of the output buffer are selected enabling the shift­and-add operation. SHADD is latched and delayed internally by one clock cycle.
The output multiplexer is also con­trolled by the SHADD input signal. This allows selection of either a filter cell accumulator, selected by ADR2-0, or the output buffer to be output to the SUM25-0 bus. Only the 26 least significant bits from either a filter cell accumulator or the output buffer are output on SUM25-0. If SHADD is LOW during two consecutive clock
cycles (low during the current and previous clock cycle), the output multiplexer selects the contents of a filter cell accumulator addressed by ADR2-0. Otherwise, the output multiplexer selects the contents of the output buffer.
If the same address remains on the ADR2-0 inputs for more than one clock cycle, SUM25-0 will not change to reflect any updates to the addressed cell accumulator. Only the result from the first selection of the cell (first clock cycle) will be output. This allows the interface of slow memory devices where the output needs to be active for more than one clock cycle. Normal FIR operation is not affected because ADR2-0 is changed sequentially.
NUMBER SYSTEMS
Data and coefficients can be repre­sented as either 8-bit unsigned or 9-bit two's complement numbers. All values are represented as 9-bit two's complement numbers internally. If the most significant or sign bit is a zero, the multiplier can multiply 8-bit unsigned numbers.
SIGNAL DEFINITIONS Power
VCC and GND
+5 V power supply. All pins must be connected.
Clock
CLK — Master Clock
The rising edge of CLK strobes all registers. All timing specifications are referenced to the rising edge of CLK.
Inputs
DIN8-0 — Data Input
9-bit data is latched into the X register of each filter cell simultaneously. The DIENB signal enables loading of the data.
CIN8-0 — Coefficient Input
9-bit coefficients are latched into the C register of Filter Cell 0. The CIENB signal enables loading of the coeffi­cients.
Outputs
SUM25-0 — Data Output
The 26-bit result from an individual filter cell will appear when ADR2-0 is used to select the filter cell result. SHADD in conjunction with ADR2-0 is used to select the output from the shift-and-add output stage.
COUT8-0 — Coefficient Output
The 9-bit coefficient output from Filter Cell 7 can be connected to the CIN8-0 coefficient input of the same LF43891 to recirculate the coefficients. COUT8-0 can also be connected to the CIN8-0 of another LF43891 to cascade the devices. The COENB signal enables the output of the coefficients.

Controls
DIENB — Data Input Enable
The DIENB input enables the X register of every filter cell. While DIENB is LOW, the X registers are loaded with the data present at the DIN8-0 inputs on the rising edge of CLK. While DIENB is HIGH, all bits of DIN8-0 are forced to zero and a rising edge of CLK will load the X register of every filter cell with all zeros. DIENB must be low one clock cycle prior to presenting the input data on the DIN8-0 input since it is latched and delayed internally.
CIENB — Coefficient Input Enable
The CIENB input enables the C and D registers of every filter cell. While CIENB is LOW, the C and appropriate D registers are loaded with the coefficient data on the rising edge of CLK. While CIENB is HIGH, the contents of the C and D registers are held and the CLK signal is ignored. By using CIENB in its active state, coefficient data can be shifted from cell to cell. CIENB must be low one clock cycle prior to presenting the coefficient data on the CIN8-0 input since it is latched and delayed inter­nally.
COENB — Coefficient Output Enable
The COENB input enables the COUT8-0 output. When COENB is LOW, the outputs are enabled. When COENB is HIGH, the outputs are placed in a high-impedance state.
DCM1-0 — Decimation Control
The DCM1-0 inputs select the num­ber of decimation registers to use (Table 1). Coefficients are passed from one cell to another at a rate determined by DCM1-0. When no decimation registers are selected, the coefficients are passed from cell to cell on every rising edge of CLK (no decimation). When one decima­tion register is selected, the coeffi­cients are passed from cell to cell on every other rising edge of CLK (2:1 decimation). When two decimation registers are selected, the coeffi­cients are passed from cell to cell on every third rising edge of CLK (3:1 decimation) and so on. DCM1-0 is latched and delayed internally.
ADR2-0 — Cell Accumulator Select
The ADR2-0 inputs select which cell’s accumulator will available at the SUM25-0 output or added to the output stage accumulator. In both cases, ADR2-0 is latched and delayed by one clock cycle. If the same address remains on the ADR2-0 inputs for more than one clock cycle, SUM25-0 will not change if the con­tents of the accumulator changes. Only the result from the first selection of the cell (first clock cycle) by ADR2-0 will be available. ADR2-0 is also used to select which accumulator to clear when ERASE is LOW.
SENBH — MSB Output Enable
When SENBH is LOW, SUM25-16 is enabled. When SENBH is HIGH, SUM25-16 is placed in a high-imped­ance state.
SENBL — LSB Output Enable
When SENBL is LOW, SUM15-0 is enabled. When SENBL is HIGH, SUM15-0 is placed in a high-imped­ance state.
RESET — Register Reset Control
When RESET is LOW, all registers are cleared simultaneously except the cell accumulators. RESET can be used with ERASE to clear all cell accumula­tors. RESET is latched and delayed internally. Refer to Table 2.
ERASE — Accumulator Erase Control
When ERASE is LOW, the cell accu­mulator specified by ADR2-0 is cleared. When RESET is LOW in conjunction with ERASE, all cell accumulators are cleared. Refer to Table 2.

9 x 9-bit Digital Filter
1. Maximum Ratings indicate stress specifications only. Functional oper­ation of these products at values beyond those indicated in the Operating Condi­tions table is not implied. Exposure to maximum rating conditions for ex­tended periods may affect reliability.
2. The products described by this spec­ification include internal circuitry de­signed to protect the chip from damag­ing substrate injection currents and ac­cumulations of static charge. Neverthe­less, conventional precautions should be observed during storage, handling, and use of these circuits in order to avoid exposure to excessive electrical stress values.
3. This device provides hard clamping of transient undershoot and overshoot. In­put levels below ground or above VCC will be clamped beginning at –0.6 V and VCC + 0.6 V. The device can withstand indefinite operation with inputs in the range of –0.5 V to +7.0 V. Device opera­tion will not be adversely affected, how­ever, input current levels will be well in excess of 100 mA.
9. AC specifications are tested with input transition times less than 3 ns, output reference levels of 1.5 V (except
tDIS test), and input levels of nominally
0 to 3.0 V. Output loading may be a resistive divider which provides for specified IOH and IOL at an output voltage of VOH min and VOL max respectively. Alternatively, a diode bridge with upper and lower current sources of IOH and IOL respectively, and a balancing voltage of 1.5 V may be used. Parasitic capacitance is 30 pF minimum, and may be distributed.
This device has high-speed outputs ca­pable of large instantaneous current pulses and fast turn-on/turn-off times. As a result, care must be exercised in the testing of this device. The following measures are recommended:
a. A 0.1 µF ceramic capacitor should be installed between VCC and Ground leads as close to the Device Under Test (DUT) as possible. Similar capacitors should be installed between device VCC and the tester common, and device ground and tester common.
11. For the tENA test, the transition is measured to the 1.5 V crossing point with datasheet loads. For the tDIS test, the transition is measured to the ±200mV level from the measured steady-state output voltage with ±10mA loads. The balancing volt­age, VTH, is set at 3.5 V for Z-to-0 and 0-to-Z tests, and set at 0 V for Z­to-1 and 1-to-Z tests.
12. These parameters are only tested at the high temperature extreme, which is the worst case for leakage current.

N = total number of device outputs C = capacitive load per output V = supply voltage F = clock frequency
b. Ground and VCC supply planes must be brought directly to the DUT socket or contactor fingers.
c. Input voltages should be adjusted to compensate for inductive ground and VCC noise to maintain required DUT input levels relative to the DUT ground pin.
10. Each parameter is shown as a min­imum or maximum value. Input re­quirements are specified from the point of view of the external system driving the chip. Setup time, for example, is specified as a minimum since the exter-
