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
specied in the
Universal Serial Bus Specication 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
Specication 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 rmware intervention. The functions of this block include:
synchronization pattern recognition, parallel/serial conversion, bit (de)stufng, CRC
checking/generation, Packet IDentier (PID) verication/generation, address
recognition, handshake evaluation/generation. There are separate SIEs in 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 ISP1161A1 DC, the 1.5 k
pull-up resistor is integrated on-chip and is not connected to VCC by default. The
connection is established through a command sent by the external/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 ISP1161A1 DC will check for USB VBUS availability before the connection can be
established. VBUS sensing is provided through pin D_VBUS.
Remark: The tolerance of the internal resistors is 25 %. This is higher than the 5 %
tolerance specied by the USB specication. However, the overall voltage
specication 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.
