OPERATION DESCRIPTION FOR EACH BLOCK
1. CRYSTAL OSCILLATION CIRCUIT AND TIMING GENERATOR
Clock required for internal operation can be generated when crystal and capacitors are connected
as shown in FIG.1 So external system clock signal may be applied to the X1 terminal at Pin 13.
However are must be taken in using system clock since the S/N ratio and noise distortion
performance can be greatly affected by Jitter, rise and fall characteristics-etc. of system clock.

2. DATA INPUT CIRCUIT
Data and LRCK are taken into the shift register at the leading edge of BCK.
As shown in the following timing example, it is necessary to input data and LRCK synchronized
with the falling edge of BCK.
In parallel mode (P/T='Ti''), input data length is fixed to 16 bits.
In serial mode (P/T="L"), input data length can be selected to 16, 18, or 20bits.

4. INTERPOLATION FILTER AND DITHER CIRCUIT
The interpolation filter linearly interpolates 8fs after the digital filter and over to 16fs in the dither
circuit, DC offset and dither have been added to Data in order to areven noise by the idling
pattern peculiar to E-A Modulation DAC. After adding the dither 384fs is over sampled in sample
and hold circuit.
5. DA CONVERSION CIRCUIT
2 times E-A modulation DA converter for 2 channels (simultaneous output type) is incorporated in
the TC9270F/N. The internal circuit construction is as shown in fig.10.
The conversion time for the bitstream output is 1/384fs. (in 384fs mode)

Latch and att signal are entered to the shift register of the LSI at the rising edge of the shift
signal.
Also, the latch signal should rise after a minimum of 1.5ps of the last data is shifted to the
