TMC2249A Datasheet Digital Mixer

Manufacturer: Fairchild (now onsemi)

Overview: .. .fairchildsemi. TMC2249A Digital Mixer 12 x 12 Bit, 60 MHz.

General Description

The TMC2249A is a high-speed digital arithmetic circuit consisting of two 12-bit multipliers, an adder and a cascadeable accumulator.

All four multiplier inputs are simultaneously accessible to the user, and each includes a userprogrammable pipeline delay of up to 16 clocks in length.

The 24-bit adder/subtractor is followed by an accumulator and 16-bit input port which allows the user to cascade multiple TMC2249As.

Key Features
