LOCKED LOOP
A 12 to 48 MHz clock multiplier PLL is integrated on-chip. No external components are needed for the operation of the
PLL.

IT CLOCK RECOVERY
The bit clock recovery circuit recovers the clock from the incoming USB data stream using 4
×
oversampling principle.
It is able to track jitter and frequency drift as specified by the USB specification.

LOCK DIAGRAM
The digital interface consists of 3 major blocks:
The Philips Serial Interface Engine (SIE) handles the USB protocol (i.e. synchronization pattern, recognition,
parallel/serial conversion, bit stuffing/de-stuffing, CRC checking/generating, PID verification/generation, address
recognition and handshake evaluation/generation)
A Memory Management Unit (MMU), controlling the buffering of data to and from the bus
An interface to the embedded 83C51 microcontroller.

FUNCTION
DESCRIPTION
P10
USB_INT_MASK
should be set to logic 1 before entering power-down mode during suspend
and reset to logic 0 when leaving power-down mode
when set to logic 1, the internal 1.5 k
resistor is connected to pin D+
the device is ready to accept a new transaction
when LOW, this signal indicates that the bus is no longer suspended
a LOW-level will reset the USB interface
when set to logic 1, V
DDD
is applied on the optional external 1.5 k
resistor
which has been placed between pins D+ and DELATT
interrupt to the microcontroller
the device is in suspended state (TDA8030 only)
remote wake-up (TDA8030 only)
if set to logic 1, the data to the bus is a command; if set to logic 0 it is data
if set to logic 1, the USB interface is selected
