EVALUATION KIT AVAILABLE MAX9205/MAX9207 10-Bit Bus LVDS Serializers General Description The MAX9205/MAX9207 serializers transform 10-bitwide parallel LVCMOS/LVTTL data into a serial highspeed bus low-voltage differential signaling (LVDS) data stream. The serializers typically pair with deserializers like the MAX9206/MAX9208, which receive the serial output and transform it back to 10-bit-wide parallel data. The MAX9205/MAX9207 transmit serial data at speeds up to 400Mbps and 660Mbps, respectively, over PCB traces or twisted-pair cables. Since the clock is recovered from the serial data stream, clock-to-data and data-to-data skew that would be present with a parallel bus are eliminated. The serializers require no external components and few control signals. The input data strobe edge is selected by TCLK_R/F. PWRDN is used to save power when the devices are not in use. Upon power-up, a synchronization mode is activated, which is controlled by two SYNC inputs, SYNC1 and SYNC2. The MAX9205 can lock to a 16MHz to 40MHz system clock, while the MAX9207 can lock to a 40MHz to 66MHz system clock. The serializer output is held in high impedance until the device is fully locked to the local system clock, or when the device is in powerdown mode. Both the devices operate from a single +3.3V supply, are specified for operation from -40°C to +85°C, and are available in 28-pin SSOP packages.

The two SYNC pins are ORed. When at least one of the two pins are asserted high for at least six cycles of TCLK, the serializer initiates a transmission of 1024 SYNC patterns. If held high after 1024 SYNC patterns have been transmitted, SYNC patterns continue to be sent until the SYNC pin is asserted low. Toggling a SYNC pin after six TCLK cycles high and before 1024 SYNC patterns have been transmitted does not affect the output of the 1024 SYNC patterns. LVCMOS/LVTTL Data Inputs.

Detailed Description The MAX9205/MAX9207 are 10-bit serializers designed to transmit data over balanced media that may be a standard twisted-pair cable or PCB traces at 160Mbps to 660Mbps. The interface may be double-terminated point-to-point or a heavily loaded multipoint bus. The characteristic impedance of the media and connected devices can range from 100Ω for a point-to-point interface to 54Ω for a heavily loaded multipoint bus. A double-terminated point-to-point interface uses a 100Ω-termination resistor at each end of the interface, resulting in a load of 50Ω. A heavily loaded multipoint bus requires a termination as low as 54Ω at each end of the bus, resulting in a termination load of 27Ω. The serializer requires a deserializer such as the MAX9206/MAX9208 for a complete data transmission application. Maxim Integrated A high-state start bit and a low-state stop bit, added internally, frame the 10-bit parallel input data and ensure a transition in the serial data stream. Therefore, 12 serial bits are transmitted for each 10-bit parallel input. The MAX9205 accepts a 16MHz to 40MHz reference clock, producing a serial data rate of 192Mbps (12 bits x 16MHz) to 480Mbps (12 bits x 40MHz). The MAX9207 accepts a 40MHz to 66MHz reference clock, producing 480Mbps to 792Mbps. However, since only 10 bits are from input data, the actual throughput is 10 times the TCLK frequency. To transmit data, the serializers sequence through three modes: initialization mode, synchronization mode, and data transmission mode. 5 MAX9205/MAX9207 10-Bit Bus LVDS Serializers Initialization Mode When V CC is applied, the outputs are held in high impedance and internal circuitry is disabled by on-chip power-on-reset circuitry. When the supply voltage reaches 2.35V, the PLL starts to lock to a local reference clock (16MHz to 40MHz for MAX9205 and 40MHz to 66MHz for MAX9207). The reference clock, TCLK, is provided by the system. A serializer locks within 2049 cycles of TCLK. Once locked, a serializer is ready to send data or SYNC patterns depending on the levels of SYNC 1 and SYNC 2. Synchronization Mode To rapidly synchronize with a deserializer, SYNC patterns can be sent. A SYNC pattern is six consecutive ones followed by six consecutive zeros repeating every TCLK period. When one or both SYNC inputs are asserted high for at least six cycles of TCLK, the serializer will initiate the transmission of 1024 SYNC patterns. The serializer will continue to send SYNC patterns if either of the SYNC input pins remains high. Toggling one SYNC input with the other SYNC input low before 1024 SYNC patterns are output does not interrupt the output of the 1024 SYNC patterns. Data Transmission Mode After initialization, both SYNC input pins must be set low by users or through a control signal from the deserializer before data transmission begins. Provided that SYNC inputs are low, input data at IN0–9 are clocked into the serializer by the TCLK input. Setting TCLK_R/F high selects the rising edge of TCLK for data strobe and low selects the falling edge. If either of the SYNC inputs goes high for six TCLK cycles at any time during data transmission, the data at IN0–9 are ignored and SYNC patterns are sent for at least 1024 TCLK cycles. A start bit high and a stop bit low frame the 10-bit data and function as the embedded clock edge in the serial data stream. The serial rate is the TCLK frequency times the data and appended bits. For example, if TCLK is 40MHz, the serial rate is 40 x 12 (10 + 2 bits) = 480Mbps. Since only 10 bits are from input data, the payload rate is 40 x 10 = 400Mbps. Power-Down Power-down mode is entered when the PWRDN pin is driven low. In power-down mode, the PLL of the serializer is stopped and the outputs (OUT+ and OUT-) are in high impedance, disabling drive current and also reducing supply current. When PWRDN is driven high, the serializer must reinitialize and resynchronize before data can be transferred. On power-up, in order for the MAX9205/MAX9207 to initialize correctly, PWRDN should remain below 0.7V until PCLK is stable and all power supplies are within specification. High-Impedance State The serializer output pins (OUT+ and OUT-) are held in high impedance when the supply voltage is first applied and while the PLL is locking to the local reference clock. Setting EN or PWRDN low puts the device in high impedance. After initialization, EN functions asynchronously. For example, the serializer output can be put into high impedance while SYNC patterns are being sent without affecting the internal timing of the SYNC pattern generation. However, if the serializer goes into high impedance, a deserializer loses PLL lock and needs to resynchronize before data transfer can resume. Table 1.

Bypass DVCC with high-frequency surface-mount ceramic 0.1µF and 0.001µF capacitors in parallel as close to the device as possible, with the smaller valued capacitor closest to DVCC. Differential Traces and Termination Output trace characteristics affect the performance of the MAX9205/MAX9207. Use controlled-impedance media and terminate at both ends of the transmission line in the media's characteristic impedance. Termination with a single resistor at the end of a pointto-point link typically provides acceptable performance. However, the MAX9205/MAX9207 output levels are specified for double-terminated point-to-point and multipoint applications. With a single 100Ω termination, the output swing is larger. TCLK RL 2 OUT+ VOD OUT- Avoid the use of unbalanced cables such as ribbon or simple coaxial cable. Balanced cables such as twisted pair offer superior signal quality and tend to generate less EMI due to canceling effects. Balanced cables tend to pick up noise as common mode, which is rejected by a differential receiver. Eliminate reflections and ensure that noise couples as common mode by running the differential traces close together. Reduce skew by matching the electrical length of the traces. Excessive skew can result in a degradation of magnetic field cancellation. The differential output signals should be routed close to each other to cancel their external magnetic field. Maintain a constant distance between the differential traces to avoid discontinuities in differential impedance. Avoid 90° turns and minimize the number of vias to further prevent impedance discontinuities. ODD IN_ VOS RL 2 EVEN IN_ TCLK_R/F = LOW Figure 2. Worst-Case ICC Test Pattern Figure 1.

A single 100Ω termination at the deserializer input is feasible and will make the differential signal swing larger. A serializer located at one end of a backplane bus driving multiple deserializers in a multidrop configuration is shown in Figure 12. A 54Ω resistor at the far end terminates the bus. This topology allows “broadcast” of data with a minimum of interconnect. The serializers can operate in a variety of topologies. Examples of double-terminated point-to-point, multidrop, point-to-point broadcast, and multipoint topologies are shown in Figures 11 through 14. Use 1% surface-mount termination resistors. A point-to-point connection terminated at each end in the characteristic impedance of the cable or PCB traces is shown in Figure 11. The total load seen by the serializer is 50Ω.

Multidrop 10 Maxim Integrated MAX9205/MAX9207 10-Bit Bus LVDS Serializers A point-to-point version of the multidrop bus is shown in Figure 13. The low-jitter MAX9150 10-port repeater is used to reproduce and transmit the serializer output over 10 double-terminated point-to-point links. Compared to the multidrop bus, more interconnect is traded for more robust hot-plug capability. The repeater eliminates nine serializers compared to 10 individual point-to-point serializer-to-deserializer connections. Since repeater jitter subtracts from the serializer-deserializer timing margin, a low-jitter repeater is essential in most high data rate applications. Multiple serializers and deserializers bused over a differential serial connection on a backplane are shown in Figure 14. The second serializer can be a backup to Board Layout For bus LVDS applications, a four-layer PCB that provides separate power, ground, and input/output signals is recommended. Separate LVTTL/LVCMOS and bus LVDS signals from each other to prevent coupling into the bus LVDS lines. ASIC ASIC ASIC MAX9206 MAX9208 MAX9205 MAX9207 MAX9150 REPEATER 100Ω the primary serializer. The typical close spacing (1in or less) of cards on a backplane reduces the characteristic impedance by as much as half the initial, unloaded value.
