Functional description
7.1 PLL clock multiplier
A 6 MHz to 48 MHz clock multiplier Phase-Locked Loop (PLL) is integrated on-chip.
This allows for the use of a low-cost 6 MHz crystal, which also minimizes EMI. No
external components are required for the operation of the PLL.
7.2 Bit clock recovery
The bit clock recovery circuit recovers the clock from the incoming USB data stream
using a 4 times over-sampling principle. It is able to track jitter and frequency drift as
specified in the Universal Serial Bus Specification Rev. 2.0
7.3 Analog transceivers
Three sets of transceivers are embedded in the chip: two are used for downstream
ports with USB connector type A; one is used for upstream port with USB connector
type B. The integrated transceivers are compliant with the Universal Serial Bus
Specification Rev. 2.0 They interface directly with the USB connectors and cables
through external termination resistors.
7.4 Philips Serial Interface Engine (SIE)
The Philips SIE implements the full USB protocol layer. It is completely hardwired for
speed and needs no firmware intervention. The functions of this block include:
synchronization pattern recognition, parallel to serial conversion, bit (de)stuffing,
CRC checking and generation, Packet IDentifier (PID) verification and generation,
address recognition, handshake evaluation and generation. There are separate SIEs
in both the HC and the DC.
7.5 SoftConnect
The connection to the USB is accomplished by bringing D
+
(for full-speed USB
devices) HIGH through a 1.5 k
pull-up resistor. In the ISP1161A DC, the 1.5 k
pull-up resistor is integrated on-chip and is not connected to V
CC
by default. The
connection is established through a command sent by the external or system
microcontroller. This allows the system microcontroller to complete its initialization
sequence before deciding to establish connection with the USB. Re-initialization of
the USB connection can also be performed without disconnecting the cable.
The ISP1161A DC will check for USB V
BUS
availability before the connection can be
established. V
BUS
sensing is provided through pin D_VBUS.
Remark:
The tolerance of the internal resistors is 25 %. This is higher than the 5 %
tolerance specified by the USB specification. However, the overall voltage
specification for the connection can still be met with a good margin. The decision to
make use of this feature lies with the USB equipment designer.
