6 / 47 page SPI TIMING: VS = AVDD = DVDD = +2.2V to +5V PGA112 ,, PGA113 PGA116, PGA117 SBOS424B – MARCH 2008 – REVISED SEPTEMBER 2008 ............................................................................................................................................ www.ti.com Boldface limits apply over the specified temperature range, TA = –40°C to +125°C. At TA = +25°C, RL = 10kΩ//CL = 100pF connected to DVDD/2, and VREF = GND, unless otherwise noted. PGA112, PGA113, PGA116, PGA117 PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Input Capacitance (SCLK, CS, and DIO pins) 1 pF Input Rise/Fall Time(1) tRFI 2 µs (CS, SCLK, and DIO pins) Output Rise/Fall Time (DIO pin)(1) tRFO CLOAD = 60pF 10 ns CS High Time (CS pin)(1) tCSH 40 ns SCLK Edge to CS Fall Setup Time(1) tCSO 10 ns CS Fall to First SCLK Edge Setup Time tCSSC 10 ns SCLK Frequency(2) fSCLK 10 MHz SCLK High Time(3) tHI 40 ns SCLK Low Time(3) tLO 40 ns SCLK Last Edge to CS Rise Setup Time(1) tSCCS 10 ns CS Rise to SCLK Edge Setup Time(1) tCS1 10 ns DIN Setup Time tSU 10 ns DIN Hold Time tHD 10 ns SCLK to DOUT Valid Propagation Delay(1) tDO 25 ns CS Rise to DOUT Forced to Hi-Z(1) tSOZ 20 ns (1) Ensured by design; not production tested. (2) When using devices in daisy-chain mode, the maximum clock frequency for SCLK is limited by SCLK rise/fall time, DIN setup time, and DOUT propagation delay. See Figure 63. Based on this limitation, the maximum SCLK frequency for daisy-chain mode is 9.09MHz. (3) tHI and tLO must not be less than 1/SCLK (max). 6 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): PGA112 PGA113 PGA116 PGA117 |
