FIN224AC 22-Bit Bi-Directional Serializer/Deserializer Features Description • Industry smallest 22-bit Serializer/Deserializer pair The FIN224AC µSerDes™ is a low-power serializer/ deserializer (SerDes) that can help minimize the cost and power of transferring wide signal paths. Through the use of serialization, the number of signals transferred from one point to another can be significantly reduced. Typical reduction is 4:1 to 6:1 for unidirectional paths. For bidirectional operation, using half duplex for multiple sources, it is possible to reach signal reduction close to 10:1. Through the use of differential signaling, shielding and EMI filters can also be minimized, further reducing the cost of serialization. The differential signaling is also important for providing a noise-insensitive signal that can withstand radio and electrical noise sources. Major reduction in power consumption allows minimal impact on battery life in ultra-portable applications. It is possible to use a single PLL for most applications including bidirectional operation. • Low power for minimum impact on battery life – Multiple power-down modes • 100nA in standby mode, 5mA typical operating conditions • Highly rolled LVCMOS edge rate option to meet regulatory requirements • Cable reduction: 25:4 or greater • Differential signaling: ––90dBm EMI when using CTL in lab conditions –Minimized shielding –Minimized EMI filter –Minimum susceptibility to external interference • Up to 22 bits in either direction • Voltage translation from 1.65V to 3.6V • High ESD protection: > 15kV HBM • Parallel I/O power supply (VDDP) range, 1.65V - 3.6V FIN224AC to FIN24AC Comparison • Can support Microcontroller or RGB pixel interface • Up to 20% power reduction Applications • Double wide CKP pulse on FIN224AC, Mode 3 • Image sensors • Rolled edge rate for deserializer outputs on FIN224AC, for single display applications • Small displays – LCD, cell phone, digital camera, portable gaming, printer, PDA, video camera, automotive • Same voltage range • Same pinout and package Ordering Information Order Number Operating Temperature Range FIN224ACGFX -30 to +70°C 42-Ball, Ultra-Small Scale Ball Grid Array (USS-BGA), Tape and Reel JEDEC MO-195, 3.5mm Wide (Slow LVCMOS Edge Rate) FIN224ACMLX -30 to +70°C 40-Terminal, Molded Leadless Package (MLP), Quad, JEDEC MO-220, 6mm Square (Slow LVCMOS Edge Rate) Package Description Packing Method Tape and Reel µSerDesTM is a trademark of Fairchild Semiconductor Corporation. © 2006 Fairchild Semiconductor Corporation FIN224AC Rev.1.1.6 www.fairchildsemi.com FIN224AC — 22-Bit Bi-Directional Serializer/Deserializer April 2011 LVCMOS LVCMOS CTL FIN224AC Serializer FIN224AC Deserializer 4 22 22 Figure 1.

Pins S1 and S2 must be set to accommodate the clock reference input frequency range of the serializer. Table 1 shows the pin programming of these options based on the S1 and S2 control pins. The DIRI pin controls whether the device is a serializer or a deserializer. When DIRI is asserted LOW, the device is configured as a deserializer. When the DIRI pin is asserted HIGH, the device is configured as a serializer. Changing the state on the DIRI signal reverses the direction of the I/O signals and generate the opposite state signal on DIRO. For unidirectional operation the DIRI pin should be hardwired to the HIGH or LOW state and the DIRO pin should be left floating. For bi-directional operation, the DIRI of the master device is driven by the system and the DIRO signal of the master is used to drive the DIRI of the slave device. The device passes and inverts the DIRI signal through the device asynchronously to the DIRO signal. Care must be taken by the system designer to ensure that no contention occurs between the deserializer outputs and the other devices on this port. Optimally the peripheral device driving the serializer should be put into a HIGHimpedance state prior to the DIRI signal being asserted. When a device with dedicated data outputs turns from a deserializer to a serializer, the dedicated outputs remain at the last logical value asserted. This value only changes if the device is once again turned around into a deserializer and the values are overwritten. Power-Down Mode: (Mode 0) Mode 0 is used for powering down and resetting the device. When both of the mode signals are driven to a LOW state, the PLL and references are disabled, differential input buffers are shut off, differential output buffers are placed into a HIGH-impedance state, LVCMOS outputs are placed into a HIGH-impedance state, and LVCMOS inputs are driven to a valid level internally. Additionally all internal circuitry is reset. The loss of CKREF state is also enabled to ensure that the PLL only powers-up if there is a valid CKREF signal. Serializer/Deserializer with Dedicated I/O Variation The serialization and deserialization circuitry is set up for 24 bits. Because of the dedicated inputs and outputs, only 22 bits of data are serialized or deserialized. DP[21:22] inputs to the serializer are transmitted to DP[23:24] outputs on the deserializer. In a typical application mode, signals of the device do not change states other than between the desired frequency range and the power-down mode. This allows for system-level power-down functionality to be implemented via a single wire for a SerDes pair. The S1 and S2 selection signals that have their operating mode driven to a “logic 0” should be hardwired to GND. The S1 and S2 signals that have their operating mode driven to a “logic 1” should be connected to a system-level power-down or reset signal. Table 1.

The basic serialization circuitry works essentially identically in these modes, but the actual data and clock streams differ depending on if CKREF is the same as the STROBE signal or not. When it is stated that CKREF does not equal STROBE, each signal is distinct and CKREF must be running at a frequency high enough to avoid any loss of data condition. CKREF must never be a lower frequency than STROBE. The exact frequency that the reference clock needs to run at depends upon the stability of the CKREF and STROBE signal. If the source of the CKREF signal implements spread spectrum technology, the minimun frequency of the spread spectrum clock should be used in calculating the ratio of STROBE frequency to the CKREF frequency. Similarly, if the STROBE signal has significant cycle-to-cycle variation, the maximum cycleto-cycle time needs to be factored into the selection of the CKREF frequency. Serializer Operation: MODE 1 or MODE 2, DIRI = 1, CKREF = STROBE Serializer Operation: MODE 3 (S1 = S2 =1), DIRI =1. CKREF Divide by 2 Mode. The PLL must receive a stable CKREF signal to achieve lock prior to any valid data being sent. The CKREF signal can be used as the data STROBE signal provided that data can be ignored during the PLL lock phase. When operating in mode 3, the effective serial speed is divided by two. This mode has been implemented to accommodate cases where the reference clock frequency is high compared to the actual strobe frequency. The actual strobe frequency must be less than or equal to 50% of the CKREF frequency for this mode to work properly. This mode, in all other ways, operates the same as described in the section where CKREF does not equal STROBE. Once the PLL is stable and locked, the device can begin to capture and serialize data. Data is captured on the rising edge of the STROBE signal and serialized. When operating in serializer mode, the internal deserializer circuitry is disabled; including the serial clock, serial data input buffers, bi-directional parallel outputs, and CKP word clock. The CKP word clock is driven HIGH. Serializer Operation: DIRI = 1, No CKREF A third method of serialization can be acheived by providing a free-running bit clock on the CKSI signal. This mode is enabled by grounding the CKREF signal and driving the DIRI signal HIGH. At power-up, the device is configured to accept a serialization clock from CKSI. If a CKREF is received, this device enables the CKREF serialization mode. The device remains in this mode even if CKREF is stopped. To re-enable this mode, the device must be powered down and then powered back up with a “logic 0” on CKREF. Serializer Operation: DIRI = 1, CKREF Does Not = STROBE If the same signal is not used for CKREF and STROBE, the CKREF signal must be run at a higher frequency than the STROBE rate to serialize the data correctly. The actual serial transfer rate remains at 13 times the CKREF frequency. A data bit value of zero is sent when no valid data is present in the serial bit stream. The operation of the serializer otherwise remains the same. Deserializer Operation Mode serial port and deserialized through use of the bit clock sent with the data. The operation of the deserializer is dependent on the data received on the DSI data signal pair and the CKSI clock signal pair. The following sections describe the operation of the deserializer under distinct serializer source conditions. References to the CKREF and STROBE signals refer to the signals associated with the serializer device generating the serial data and clock signals that are inputs to the deserializer. When operating in deserializer mode, the internal serializer circuitry is disabled, including the parallel data input buffers. If there is a CKREF signal provided, the CKSO serial clock continues to transmit bit clocks. Upon power-up (S1 or S2 = 1), deserializer output data pins are driven LOW until valid data is passed through the deserializer. Deserializer Operation: DIRI = 0 (Serializer Source: CKREF Does Not = STROBE) The logical operation of the deserializer remains the same if the CKREF is equal in frequency to the STROBE or at a higher frequency than the STROBE. The actual serial data stream presented to the deserializer is different because it has non-valid data bits sent between words. The duty cycle of CKP varies based on the ratio of the frequency of the CKREF signal to the STROBE signal. The frequency of the CKP signal is equal to the STROBE frequency. In modes 1 and 2, the CKP LOW time equals half of the CKREF period of the serializer. In mode 3, the CKP LOW is equal to the CKREF period. The CKP HIGH time is approximately equal to the STROBE period, minus the CKP LOW time. Deserializer Operation: DIRI = 0 (Serializer Source: CKREF = STROBE) When the DIRI signal is asserted LOW, the device is configured as a deserializer.

The input buffers are only operational when the device is operating as a serializer. When the device is operating as a deserializer, the inputs are gated off to conserve power. The LVCMOS 3-STATE output buffers are rated for a source / sink current of approximately 0.5mA at 1.8V. The outputs are active when the DIRI signal and either S1 or S2 is asserted HIGH. When the DIRI signal and either S1 or S2 is asserted LOW, the bi-directional LVCMOS I/Os is in a HIGH-Z state. Under purely capacitive load conditions, the output swings between GND and VDDP. When S1 or S2 initially transitions HIGH, the initial state of the deserializer LVCMOS outputs is zero. Unused LVCMOS input buffers must be either tied off to a valid logic LOW or a valid logic HIGH level to prevent static current draw due to a floating input. Unused LVCMOS output should be left floating. Unused bi-directional pins should be connected to GND through a high-value resistor. If a FIN224AC device is configured as an unidirectional serializer, unused data I/O can be treated as unused inputs. If the FIN224AC is hardwired as a deserializer, unused data I/O can be treated as unused outputs. © 2006 Fairchild Semiconductor Corporation FIN224AC Rev.1.1.6 www.fairchildsemi.com 7 SerDes Serializer PIXCLK_M A6 B5 CKREF STROBE GPIO_MODE F6 F5 J6 DIRI S2 S1 J5 J4 J3 F3 J2 J1 F2 F1 E2 E1 D2 D1 C2 B1 B2 A1 C3 A2 B3 A3 C4 A4 B4 A5 DP24 DP23 DP22 DP21 DP20 DP19 DP18 DP17 DP16 DP15 DP14 DP13 DP12 DP11 DP10 DP9 DP8 DP7 DP6 DP5 DP4 DP3 DP2 DP1 U22 J6 F5 F6 B5 A6 STROBE CKREF B6 DIRO DIRO CKP C1 DSO+/DSIDSO-/DSI+ D6 D5 D5 D6 DSO-/DSI+ DSO+/DSI- CKSOCKSO+ C6 C5 E6 E5 CKSICKSI+ CKSICKSI+ E6 E5 C6 C5 CKSOCKSO+ F4 E4 D3 VDDA VDDS VDDP 2.8V VDDA VDDS VDDP C6 1nF TP5 2.8V 1.8V F4 E4 D3 FIN224AC S1 S2 DIRI B6 D4 E3 LCD_ENABLE_M LCD_VSYNC_M LCD_HSYNC_M LCD17_M LCD16_M LCD15_M LCD14_M LCD13_M LCD12_M LCD LCD11_M Controller LCD10_M Out LCD9_M LCD8_M LCD7_M LCD6_M LCD5_M LCD4_M LCD3_M LCD2_M LCD1_M LCD0_M SerDes Deserializer FIN224AC C3 .01uF .01µF 2.8V C12 .01uF .01µF C10 C11 GN D GN D U20 CKP C1 DP24 DP23 DP22 DP21 DP20 DP19 DP18 DP17 DP16 DP15 DP14 DP13 DP12 DP11 DP10 DP9 DP8 DP7 DP6 DP5 DP4 DP3 DP2 DP1 J5 J4 J3 F3 J2 J1 F2 F1 E2 E1 D2 D1 C2 B1 B2 A1 C3 A2 B3 A3 C4 A4 B4 A5 PIXCLK_S LCD_ENABLE_S LCD_VSYNC_S LCD_HSYNC_S LCD17_S LCD16_S LCD15_S LCD14_S LCD13_S LCD12_S LCD11_S LCD LCD10_S LCD9_S Display LCD8_S In LCD7_S LCD6_S LCD5_S LCD4_S LCD3_S LCD2_S LCD1_S LCD0_S E3 D4 VDDP GN D GN D TP6 2.2uF 1nF 2.2µF Assumptions: 1) 18-bit Unidirectional RGB Application 2) Mode 3 Operation (10 Mhz to 20Mhz CKREF) 3) VDDP= (1.65V to 3.6V) Figure 5.

Figure 6. FIN224AC Microcontroller Flex Circuit Design Guidelines The serial I/O information is transmitted at a high serial rate. Care must be taken implementing this serial I/O flex cable. The following best practices should be used when developing the flex cabling or Flex PCB: Keep all four differential wires the same length. Allow no noisy signals over or near differential serial wires. Example: No LVCMOS traces over differential wires. Use only one ground plane or wire over the differential serial wires. Do not run ground over top and bottom. Do not place test points on differential serial wires. Use differential serial wires a minimum of 2cm away from the antenna. © 2006 Fairchild Semiconductor Corporation FIN224AC Rev.1.1.6 www.fairchildsemi.com 8 FIN224AC — 22-Bit Bi-Directional Serializer/Deserializer Application Mode Diagrams Stresses exceeding the absolute maximum ratings may damage the device.

Skew is measured from either the rising or falling edge of CKSO clock to the rising or falling edge of data (DSO). Signals are edge aligned. Both outputs should have identical load conditions for this test to be valid. 4. The power-down time is a function of the CKREF frequency prior to CKREF being stopped HIGH or LOW and the state of the S1/S2 mode pins. The specific number of clock cycles required for the PLL to be disabled varies dependent upon the operating mode of the device. 5. Signals are transmitted from the serializer source synchronously. Note that, in some cases, data is transmitted when the clock remains at a HIGH state. Skew should only be measured when data and clock are transitioning at the same time. Total measured input skew would be a combination of output skew from the serializer, load variations, and ISI and jitter effects. 6. a = (1/f)/13) Rising edge of CKP appears approximately 13 bit times after the falling edge of the CKP output. Falling edge of CKP occurs approximately eight bit times after a data transition or six bit times after the falling edge of CKSO. Variation of the data with respect to the CKP signal is due to internal propagation delay differences of the data and CKP path and propagation delay differences on the various data pins. Note that if the CKREF is not equal to STROBE for the serializer, the CKP signal does not maintain a 50% duty cycle.The low time of CKP remains 13 bit times.
