MITSUBISHI 〈DIGITAL ASSP 〉 〉 MITSUBISHI 〈DIGITAL ASSP M66260FP M66260FP 8 CROSSPOINT × 4 CROSSPOINT SWITCH MIXING FUNCTION 8×4 SWITCH withwith MIXING FUNCTION DESCRIPTION The M66260 is an integrated circuit consisiting of a 8 × 4 cross point switch capable of selecting 32 analog switches with mixing registance respectively by serial control inputs. Using the M66260 with an external standard Op-Amp, 8 analog input signals can be mixed and output to any of 4 outputs freely by serial control inputs. FEATURES Serial data input type Switching and mixing function possible with standard OpAmp. Switch matrix can be extended to 8 × 8 or 8 × 12 by combining 2 or 3 ICs in parallel. Excellent crosstalk characteristic .......................... –90 dB [f = 3 kHz, VIN = –10dBV] (typ.) APPLICATION Line switching with mixing function of telephone and communication equipments. FUNCTION Serial data input A is the data input of the first step of 32 BIT SHIFT REGISTER and when latch enable input LE is “L”, the signal of A shifts shifting registers one by one when shift clock input CKs changes from “L” to “H”, in units of 32 bits.
