FIN1217 * FIN1218 * FIN1215 * FIN1216 LVDS 21-Bit Serializers/De-Serializers
October 2003 Revised October 2004
FIN1217 * FIN1218 * FIN1215 * FIN1216 LVDS 21-Bit Serializers/De-Serializers
General Description
The FIN1217 and FIN1215 transform 21-bit wide parallel LVTTL (Low Voltage TTL) data into 3 serial LVDS (Low Voltage Differential Signaling) data streams. A phaselocked transmit clock is transmitted in parallel with the data stream over a separate LVDS link. Every cycle of transmit clock 21 bits of input LVTTL data are sampled and transmitted. The FIN1218 and FIN1216 receive and convert the 3 serial LVDS data streams back into 21 bits of LVTTL data. Refer to Table 1 for a matrix summary of the Serializers and Deserializers available. For the FIN1217, at a transmit clock frequency of 85 MHz, 21 bits of LVTTL data are transmitted at a rate of 595 Mbps per LVDS channel. These chipsets are an ideal solution to solve EMI and cable size problems associated with wide and high-speed TTL interfaces.

Note 6: Absolute maximum ratings are DC values beyond which the device may be damaged or have its useful life impaired. The datasheet specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet specifications. Note 7: 100mV VCC noise should be tested for frequency at least up to 2 MHz. All the specification below should be met under such a noise.

Transmitter Output Data Jitter (f = 65 MHz) (Note 13)
Transmitter Output Data Jitter (f = 85 MHz) (FIN1217 only) (Note 13)
Note 12: Outputs of all transmitters stay in 3-STATE until power reaches 2V. Both clock and data output begins to toggle 10ms after VCC reaches 3V and Power-Down pin is above 1.5V. Note 13: This output data pulse position works for both transmitter with 21 TTL inputs except the LVDS output bit mapping difference (see Figure 15). Figure 16 shows the skew between the first data bit and clock output. Also 2-bit cycle delay is guaranteed when the MSB is output from transmitter. Note 14: This jitter specification is based on the assumption that PLL has a ref clock with cycle-to-cycle input jitter less than 2ns.

Note: This jitter pattern is used to test the jitter response (Clock Out) of the device over the power supply range with worst jitter 3ns (cycle-to-cycle) clock input. The specific test methodology is as follows: * * Switching input data TxIn0 to TxIn20 at 0.5 MHz, and the input clock is shifted to left -3ns and to the right +when data is HIGH (by switching between CLK1 and CLK2 in Figure 11) The 3ns cycle-to-cycle input jitter is the static phase error between the two clock sources. Jumping between two clock sources to simulate the worst case of clock edge jump (3 ns) from graphical controllers. Cycle-to-cycle jitter at TxCLK out pin should be measured cross VCC range with 100mV noise (VCC noise frequency <2 MHz).
