HSP45102 - 12-Bit Numerically Controlled Oscillator

NAME VCC GND P0-1 CLK SCLK SEL_L/M SFTEN MSB/LSB ENPHAC SD TXFR I I I I I I I I I TYPE +5V power supply pin. Ground Phase modulation inputs (become active after a pipeline delay of four clocks). A phase shift of 0, 90, 180, or 270 degrees can be selected as shown in Table 1. NCO clock. (CMOS level) .

HSP45102 Data Sheet January 1999 File Number 2810.6 12-Bit Numerically Controlled Oscillator The Intersil HSP45102 is Numerically Controlled Oscillator (NCO12) with 32-bit frequency resolution and 12-bit output. With over 69dB of spurious free dynamic range and worst case frequency resolution of 0.009Hz, the NCO12 provides signiﬁcant accuracy for frequency synthesis solutions at a competitive price. The frequency to be generated is selected from two frequency control words. A single control pin.
