6.9 Bit clock recovery
The bit clock recovery circuit recovers the clock from the incoming USB data stream
using a 4
×
oversampling principle. It is able to track jitter and frequency drift as
specified by the USB Specification Rev. 1.1
6.10 Voltage regulator
A 5 to 3.3 V DC-DC regulator is integrated on-chip to supply the analog transceiver
and internal logic. This can also be used to supply the terminal 1.5 k
pull-up resistor
on the D
+
line of the upstream connection.
6.11 PLL clock multiplier
A 6 to 48 MHz clock multiplier Phase-Locked Loop (PLL) is integrated on-chip. This
allows for the use of low-cost 6 MHz crystals. The low crystal frequency also
minimizes Electro-Magnetic Interference (EMI). The PLL requires no external
components.
6.12 Overcurrent detection
An overcurrent detection circuit for downstream ports has been integrated on-chip. It
is self-reporting, resets automatically, has a low trip time and requires no external
components. The ISP1130 supports individual overcurrent detection.
6.13 Power-on reset
The ISP1130 has an internal power-on reset circuit, which generates a reset pulse
when the supply voltage is switched on and when the supply voltage drops below a
predetermined threshold value (see
Table 89
).
6.14 I
2
C-bus interface
A serial I
2
C-bus interface (single master or slave, bit rate up to 400 kHz) is provided
to read vendor ID, product ID and other configuration data from an external EEPROM
(e.g., Philips PCF8582 or equivalent). For more information, see
Section 11
.
The I
2
C-bus interface timing is programmable and complies with the standard mode
and the Fast mode of operation as described in The I
2
C-bus and how to use it order
number 9398 393 40011.
