Functional description

7.1 PLL clock multiplier

A 6 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

× over-sampling principle. It is able to track jitter and frequency drift as

speciﬁed by the

USB Speciﬁcation Rev. 1.1.

7.3 Analog transceivers

Three sets of transceiver 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 1.1. 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/serial conversion, bit (de)stufﬁng, CRC

checking/generation, Packet IDentiﬁer (PID) veriﬁcation/generation, address

recognition, handshake evaluation/generation. There are separate SIE in both the HC

and the DC.

7.5 SoftConnect (in DC)

The connection to the USB is accomplished by bringing D

+ (for high-speed USB

devices) HIGH through a 1.5 k

Ω pull-up resistor. In the ISP1161 the 1.5 kΩ 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 ISP1161 DC will check for USB VBUS availability before the connection can be

established. VBUS sensing is provided through pin D_VBUS.

Remark: Note that the tolerance of the internal resistors is 25%. This is higher than

the 5% tolerance speciﬁed by the USB speciﬁcation. However, the overall VSE 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.
