Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor's system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

FIN1215 / FIN1216 / FIN1217/ FIN1218 LVDS 21-Bit Serializers / De-Serializers Features Description The FIN1217 and FIN1215 transform 21-bit wide parallel LVTTL (Low-Voltage TTL) data into three serial LVDS (Low-Voltage Differential Signaling) data streams. A phase-locked 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. Low Power Consumption 20MHz to 85MHz Shift Clock Support 50% Duty Cycle on the Clock Output of Receiver 1V Common-mode Range ~1.2V Narrow Bus Reduces Cable Size and Cost High Throughput: 1.785Gbps Up to 595Mbps per Channel Internal PLL with No External Components Compatible with TIA/EIA-644 Specification Offered in 48-lead TSSOP Packages The FIN1216 and FIN1218 receives and converts the three serial LVDS data streams back into 21 bits of LVTTL data. Table 1 provides a matrix summary of the serializers and de-serializers available. For the FIN1217, at a transmit clock frequency of 85MHz, 21 bits of LVTTL data are transmitted at a rate of 595Mbps per LVDS channel. These chipsets solve EMI and cable size problems associated with wide and high-speed TTL interfaces.

The minimum and maximum pulse position values are based on the bit position of each of the seven bits within the LVDS data stream across PVT (Process, Voltage Supply, and Temperature). Figure 22. Receiver LVDS Input Skew Margin FIN1215 / FIN1216 / FIN1217 -- LVDS 21-Bit Serializers / De-Serializers AC Loadings and Waveforms (Continued) Note: This jitter pattern is used to test the jitter response (clock out) of the device over the power supply range with worst jitter ns (cycle-to-cycle) clock input. The specific test methodology is as follows: Switching input data TxIn0 to TxIn20 at 0.5MHz and the input clock is shifted to left -3ns and to the right +3ns 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 (3ns) from graphical controllers. Cycle-to-cycle jitter at TxCLK out pin should be measured cross VCC range with 100mV noise (VCC noise frequency <2MHz). Figure 23.
