DS Series Encoder/Decoder

Data Guide

Description

The DS Series encoder/decoder is ideal for remote control applications. It is used to transfer the status of up to eight buttons or contacts across a wireless link. Addressing is accomplished by the logic state of 10 pins, typically connected to DIP switches. The encoder and decoder are in the same part, selected by the state of one pin, which is a beneﬁt for volume purchasing and production.

Warning: None of the input lines have internal pull-up or pull-down

resistors. The input lines must always be in a known state (either GND or VCC) at all times or the operation may not be predictable. The designer must ensure that the input lines are never ﬂoating, either by using external resistors, by tying the lines directly to GND or VCC, or by use of other circuits to control the line state.

Protocol Selection. The state of this line determines the data structure and protocol used by the encoder / decoder. Pull low to use the Holtek data structure, pull high to use the serial structure.

Data Lines. When in Encoder Mode, the states of these lines are captured when the TE line goes high and are encoded for transmission. When in Decoder Mode, these lines reproduce the states of the encoder’s data lines upon reception of a valid packet.

Encoder/Decoder Select. The state of this line determines if the DS is an encoder or a decoder. If the line is high, then the DS enters Encoder Mode. If the line is low, then it enters Decoder Mode. This line is checked once upon power up.

Data Line Conﬁguration. Determines whether a low on a data line is interpreted as a zero bit or an open bit. See the Input Type Selection section.

Address Conﬁguration 0. With A_CFG1, determines the address bit type interpretation. See the Input Type Selection section.

Address Conﬁguration 1. With A_CFG0, determines the address bit type interpretation. See the Input Type Selection section.

Address Lines. The DS has ten address lines that are used to set a local address.

When in Encoder Mode, this line is the Transmit Enable line. When it is pulled high, the encoder records the states of the data and address lines, assembles them into a packet, and outputs the packet on the DOUT line three times. When in Decoder Mode, this line is the data input from the receiver.

When in Encoder Mode, this line is the data output that is connected to the transmitter. When in Decoder Mode, this line is the Valid Transmit indicator and goes high when a valid packet is received.

Theory of Operation

The DS Series is a remote control encoder and decoder that offers two protocols in one part based on the state of the P_SEL line. The ﬁrst protocol operates with the Holtek® HT640 encoder and HT658 decoder. The second is a serial protocol that offers more noise immunity and faster response time while keeping the simple addressing. The DS can operate as either an encoder or decoder based on the state of the E/D_SEL line. It does not operate as both simultaneously.

When set as an encoder it monitors the state of the TE line. When the line is high the DS records the states of the data and address lines, assembles them into a packet and outputs the packet three times. The data lines can be connected to switches or contacts. The address lines can be set with DIP switches or cut traces on a PCB.

When set as a decoder the DS receives packets and validates them. The validation includes checking the bit timings and comparing the received address to the local address line settings. Two matching packets must be received consecutively. If the timings are good and the addresses match, the DS sets its data lines to match the received states. These lines can be connected to the application circuitry to be controlled.

When the TE/DIN line is low, the DS goes into a low power sleep mode.

Note: The input lines on the DS are not tri-state. They must be pulled

high or low and cannot be left ﬂoating. This is a key difference between the DS and the Holtek® parts.

Setting the Address

The DS Series has ten address lines. This allows the formation of up to 1,022 (2

These lines may be hardwired or conﬁgured via a microprocessor, DIP switch or jumpers. The receiver’s address line states must match the transmitter’s exactly for a transmission to be recognized. If the addresses do not match, then the decoder takes no action.

– 2) unique transmitter-receiver relationships.

Note: The DS decoder rejects packets with addresses set to all high

or all low. At least one address line must be different from the rest. The encoder does transmit all addresses, but the decoder rejects packets with all address lines set the same.

– – – –

Initial Operation

On power-up, the E/D_SEL line is tested to determine if the DS operates as an encoder or a decoder. If the line is high, the DS enters Encoder Mode. If low, it enters Decoder Mode. This is checked once on power-up. Once the operating mode is selected, the data-line direction is set. In either mode a rising edge on the TE/DIN line wakes the device from low-power sleep.

Encoder Mode

Once the DS enters Encoder Mode, it tests the state of the TE line. If it is high, the P_SEL line is checked to determine which protocol to use. Then the encoder records the states of the Data and Address lines and assembles a packet. When the Holtek® protocol is selected, the DS outputs the packet on the DOUT line three times. With the Serial protocol, it sends two packets, checking the states of the data lines each time. The second packet is the logical inversion of the ﬁrst packet, ensuring a 50% duty cycle, which is an advantage for FCC testing. The DS then checks the state of the TE line again. It repeats this process for as long as the TE line is high. Once it goes low, the DS goes to sleep until TE is pulled high.

Decoder Mode

When the DS enters Decoder Mode, it checks the state of the DIN line. If it is high, the P_SEL line is checked to set which protocol is used and the decoder receives the data. It compares the address in the received packet to its local address lines. If they match, the data is stored and a second packet is received. With the Holtek® protocol, the decoder compares the two packets. If they match, the received data bits are output on the data lines and the VT line is pulled high. This protocol compares each packet with the previous one looking for a match. The serial protocol requires two matching packets for initial activation, then updates the lines on each subsequent packet. The DS then looks for the next packet on the DIN line.

With the Holtek® protocol, once no valid data is received (there is a mismatch of address, data, or bit timings), the Data and VT lines are pulled low and the DS goes to sleep until DIN is pulled high. The Serial protocol holds the output states until a 130ms timer runs out.

The Holtek® protocol compares two packets and, if they match, sets the outputs. If a data line is toggled during a transmission (D1 is activated while D0 is already active) then the received packet does not match the previous packet and the output lines are pulled low until the next packet arrives. This causes all of the outputs to brieﬂy cut out when a line is toggled. The serial protocol uses a timer to prevent this cut out.

Holtek Data and Packet Structure

The Holtek® encoders and decoders have tri-state input lines. They recognize three distinct states: one, zero and open. A one bit is set when the line is at VCC. A zero bit is set when the line is at ground. An open bit is set when the line is not connected or ﬂoating.

Input Type Selection

The DS Series is designed to be operable with Holtek® encoders and decoders, but there is one key condition. The Holtek® encoders and decoders have tri-state input lines but the DS has bi-state lines. Tri-state inputs are connected to ground for zero bits, VCC for one bits, or left unconnected for open bits. Since the DS cannot match this operation the D_CFG, A_CFG0 and A_CFG1 lines are provided to select the desired interpretation. The settings must match on both ends.

Pulling D_CFG high conﬁgures the data inputs as one and zero. A high on a data line is interpreted as a one bit and a low on the line is interpreted as a zero bit. Pulling D_CFG low conﬁgures the data inputs as one and open. A high on a data line is interpreted as a one bit and a low on the line is interpreted as an open bit. The decoder outputs open data bits as logic low. This is shown in Figure 12.

Serial Data and Packet Structure

The serial protocol encodes the address and data lines as binary bits that follow logic low and logic high voltage levels. The logic states of each line are recorded and placed into bytes. A checksum is calculated on the bytes and appended to the end of the packet. A preamble and a noise ﬁlter are added to the front. The packet is shown in Figure 14.

2 Byte Preamble

0 1010 1010 10 1010 1010

Figure 14: Serial Protocol Packet Structure

1ms Low 1ms High

The bytes are output in serial fashion at 4,800bps. The DS outputs the packet twice, with the second packet being the logical inversion of the ﬁrst. This ensures that the duty cycle of the data is always 50%. Adding in the blanking period between packets lowers the duty cycle. This is important for FCC certiﬁcation where the transmitter output power level is a function of the data duty cycle.

This protocol only uses binary states, so the D_CFG, A_CFG0 and A_CFG1 lines are ignored.

Operation with the Holtek® HT640 and HT658

The DS is fully compatible with the Holtek® HT640 encoder and the HT658, and HT648L decoders. The primary operational difference is that the DS Series has bi-state address lines (high or low) while the Holtek® parts have tri-state lines (high, low or ﬂoating). Since these are distinct states for the Holtek® parts, three conﬁguration lines are used to select how the inputs are interpreted. This accommodates most applications using the Holtek® parts.

Note: Contact Linx for compatability with other Holtek® encoder/

decoder products.

The states of the A_CFG0 and A_CFG1 lines determine how the DS Series interprets the states of its address lines. These lines allow for the use of any two of Holtek®’s three states at a time. The states are outlined in Figure 13.

The state of the D_CFG line determines how the DS Series interprets the states of its data lines when in Encoder Mode. This allows for the use of any two of Holtek®’s three states at a time. The states are outlined in Figure

12.

The serial protocol is much more immune to bit edge jitter than the Holtek® protocol. This gives much better range and performance within that range. This also gives the DS better immunity to noise from motors, switching power supplies, high current drivers and other noise sources.

This protocol updates the data line states on every packet. This, combined with a faster data rate, give the serial protocol a much faster response time than the Holtek® protocol (36.5ms typical compared to 135ms).

The serial protocol compares two packets as part of the data validation, but also includes a timer that keeps the outputs stable in the case of mismatched packets. This prevents the outputs from turning off at the loss of one packet or when a data line is toggled while another one is active. This helps prevent chattering of relays and other electro-mechanical devices that are not designed for rapid switching. The outputs turn off after 130ms with no valid data.

– – – –

While the DS Series is not fully compatible with the Holtek® parts because of the lack of tri-state lines, the use of the conﬁguration lines allows most applications to make a seamless transition to the DS.
