4. Functional Description

4.1

Read Operation

After power up, once the e5530 has detected the incoming RF field, the IC continuously trans-

mits the identification code as long as the RF signal is applied. The transition from the last bit to

bit 1 of the next sequence occurs without interruption. Data is transmitted by damping the incom-

ing RF signal by an internal load. These load changes are detected by the reader station.

Different kinds of modulation and bitrates are optionally available.

4.2

4.3

Rectifier

For internal power supply, an on-chip bridge rectifier is used which consists of two diodes and

two n-channel transistors. A Zener diode, which protects the circuit against overvoltage on the

coil inputs, and a smoothing capacitor for the internal supply are also provided.

Damping Load

Incoming RF will be damped by the power consumption of the IC itself and by an internal load,

which is controlled by the modulator. The loads are p-channel transistors connected between

_DDand the coil inputs.

The IDIC includes mask options for the load circuit: single-side, double-side and alternate-side

modulation.

There are four modulation methods available which can be selected by fuses. The

corresponding timing diagram is shown in Figure 4-1 on page 5.

4.4

4.5

FSK Modulation

Logical data “1” and “0” are represented as two different frequencies of damping. The frequency

for “1” is RF divided by 10, a “0” divides RF by 8.

PSK Modulation

The external coil is damped with a carrier frequency of RF/2. A logical “1” causes (at the end of

the bit period) a 180° phase shift on the carrier frequency, while a logical “0” causes no phase

shift.

4.6

4.7

Biphase Modulation

Logical “1” produces a signal which is the same as the internal bitclock. A logical “0” produces no

signal change in the middle of the bit period.

Manchester Modulation

A logical “1” causes a rising edge in the middle of a bit period (i.e., switch damping off), while a

logical “0” causes a falling edge (i.e., switch damping on).

A combination of Biphase- and FSK-modulation is also optionally available. The available com-

binations between the modulation types and the bitrates are shown in Table 4-1 on page 5

“Transmission Options”.
