FEATURES
1.1
Hardware
24-bit Philips 70 MIPS DSP core (24-bit data path and
12/24-bit coefficient path)
1.5 kbyte of downloadable DSP program memory
(PRAM)
2 kbyte of DSP program memory (PROM)
2.5 kbyte of re-programmable DSP data memory
(XRAM)
512 byte of re-programmable DSP coefficient memory
(YRAM)
Four stereo digital serial inputs (8 channels) with
common BCK and WS. To these inputs the I

S-bus
format or LSB-justified formats can be applied
One stereo bitstream DAC (2 channels) with 64 fold
oversampling and noise shaping
Selectable clock output (pin SYSCLK) for external slave
devices (512f
s
to 128f
s
)
Four stereo digital serial outputs (8 channels) with
selectable I
2
S-bus or LSB-justified format
Two SPDIF inputs combined with digital serial input
On-board WS_PLL generates clock for on-board DAC
and output pin SYSCLK
I
2
C-bus controlled (including fast mode)
Programmable Phase-Locked Loop (PLL) derives the
clock for the DSP from the CLK_IN input
40 to +85
°
C operating temperature range
supply voltage only 3.3 V
All digital inputs are tolerant for 5 V input levels
Power-down mode for low current consumption in
standby mode
Optimized pinning for applications with other Philips
DACs (such as UDA1334, UDA1355 and UDA1328).
