53 / 87 page  TMS320C5x, TMS320LC5x DIGITAL SIGNAL PROCESSORS SPRS030A – APRIL 1995 – REVISED APRIL 1996 53 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251–1443 external divide-by-two clock option An external frequency source can be used by injecting the frequency directly into X2/CLKIN with X1 left unconnected. Refer to Table 9 and Table 10 for appropriate configuration of the CLKMD1, CLKMD2 and CLKMD3 pins to generate the external divide-by-2 clock option. The external frequency injected must conform to the specifications listed in the timing requirements table. switching characteristics over recommended operating conditions [ H = 0.5 tc(CO)] (’320C5x only) (see Figure 13) PARAMETER ’320C5x-40 ’320C5x-57 UNIT PARAMETER MIN TYP MAX MIN TYP MAX UNIT tc(CO) Cycle time, CLKOUT1 48.8 2tc(CI) † 35 2tc(CI) † ns td(CIH-COH/L) Delay time, X2/CLKIN high to CLKOUT1 high / low 3 11 20 3 11 20 ns tf(CO) Fall time, CLKOUT1 5 5 ns tr(CO) Rise time, CLKOUT1 5 5 ns tw(COL) Pulse duration, CLKOUT1 low H – 3 H H + 2 H – 3 H H + 2 ns tw(COH) Pulse duration, CLKOUT1 high H – 3 H H + 2 H – 3 H H + 2 ns PARAMETER ’320C5x-80 ’320C5x-100 UNIT PARAMETER MIN TYP MAX MIN TYP MAX UNIT tc(CO) Cycle time, CLKOUT1 25 2tc(CI) † 20 2tc(CI) † ns td(CIH-COH/L) Delay time, X2/CLKIN high to CLKOUT1 high / low 1 9 18 1 9 18 ns tf(CO) Fall time, CLKOUT1 4 4 ns tr(CO) Rise time, CLKOUT1 4 4 ns tw(COL) Pulse duration, CLKOUT1 low H – 3 H H + 2 H – 3 H H + 2 ns tw(COH) Pulse duration, CLKOUT1 high H – 3 H H + 2 H – 3 H H + 2 ns switching characteristics over recommended operating conditions [ H = 0.5 tc(CO)] (’320LC5x only) (see Figure 13) PARAMETER ’320LC5x-40 ’320LC5x-50 ’320LC5x-80 UNIT PARAMETER MIN TYP MAX MIN TYP MAX MIN TYP MAX UNIT tc(CO) Cycle time, CLKOUT1 50 2tc(CI) † 40 2tc(CI) † 25 2tc(CI) † ns td(CIH-COH/L) Delay time, X2/CLKIN high to CLKOUT1 high / low 3 11 20 3 11 20 1 9 18 ns tf(CO) Fall time, CLKOUT1 5 5 4 ns tr(CO) Rise time, CLKOUT1 5 5 4 ns tw(COL) Pulse duration, CLKOUT1 low H – 3 H H + 2 H – 3 H H + 2 H – 3 H H + 2 ns tw(COH) Pulse duration, CLKOUT1 high H – 3 H H + 2 H – 3 H H + 2 H – 3 H H + 2 ns † This device utilizes a fully static design and, therefore, can operate with tc(Cl) approaching infinity. The device is characterized at frequencies approaching 0 Hz but is tested at tc(CO) = 300 ns to meet device test time requirements. |
