A phase- 50% duty cycle on the clock output of receiver locked transmit clock is transmitted in parallel with the data ±1V common-mode range around 1.2V stream over a separate LVDS link. Every cycle of transmit clock 21 bits of input LVTTL data are sampled and trans-Narrow bus reduces cable size and cost mitted. High throughput (up to 1.785 Gbps throughput) The FIN1218 and FIN1216 receive and convert the 3 serialUp to 595 Mbps per channel LVDS data streams back into 21 bits of LVTTL data. Refer Internal PLL with no external component to Table 1 for a matrix summary of the Serializers and De- Compatible with TIA/EIA-644 specification serializers available. For the FIN1217, at a transmit clock Devices are offered in 48-lead TSSOP packages 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.
